The presence of a murmur leads to an echocardiographic examination and the correct diagnosis. The swing phase also involves fexion o the hip so that the ree limb accelerates aster than the orward movement o the body. During this procedure, part o the ductus deerens is ligated and/or excised through an incision in the superior part o the scrotum. The anterior and posterior segmental medullary arteries are derived rom spinal branches o the ascending cervical, deep cervical, vertebral, posterior intercostal, and lumbar arteries. Coronary Collateral Circulation the branches o the coronary arteries are generally considered to be unctional end arteries (arteries that supply regions o the myocardium lacking sucient anastomoses rom other large branches to maintain viability o the tissue should occlusion occur). The peritoneal cavity is rst infated with carbon dioxide gas, distending the abdominal wall, to provide viewing and working space. Lymphatic vessels rom the inerior hal o the rectum drain directly to sacral lymph nodes or, especially rom the distal ampulla, ollow the middle rectal vessels to drain into the internal iliac lymph nodes. Radiographs in later stages may reveal vertebral collapse (compression ractures) and increased thoracic kyphosis. In males, the atty layer is greatly diminished in the urogenital triangle, being replaced altogether in the penis and scrotum with smooth (dartos) muscle. This variation must be kept in mind when perorming venesections or withdrawing blood or making intravenous injections. The major structures in the mediastinum are also surrounded by blood and lymphatic vessels, lymph nodes, nerves, and at. On the other hand, if surgery is delayed there will be secondary changes of the valve which will increase the difficulty of repair and reduce the probability that repair will be successful. In the absence o the support provided by the ischio-anal at, rectal prolapse is relatively common. This structure may vary in size rom a small protuberance to a complete rib that occurs bilaterally about 60% o the time. Spine of scapula Lateral view the deep posterior axio-appendicular (axioscapular or thoraco-appendicular) muscles are the levator scapulae and rhomboids. The sympathetic innervation is rom the lumbar spinal cord levels via the lumbar splanchnic nerves, and the parasympathetic innervation is rom the sacral levels via the pelvic splanchnic nerves. The sartorius lies supercially in the anterior compartment, within its own relatively distinct ascial sheath. Small black arrows indicate the ow (leaking) o interstitial uid out o blood capillaries and (absorption) into the lymphatic capillaries. An alternative to early, direct anastomosis is delayed repair following placement of a systemic arterial shunt to the discontinuous pulmonary artery. In fact, in some patients, there is a complete failure of transition from the normal fetal pulmonary vasculature to the more mature state in which smooth muscle extends less distally into the pulmonary artery tree. The descending part o the duodenum runs ineriorly, curving around the head o the pancreas. Hiccups have many causes, such as indigestion, diaphragm irritation, alcoholism, cerebral lesions, and thoracic and abdominal lesions, all which disturb the phrenic nerves. This ascia is continuous with the antebrachial ascia, the deep ascia o the orearm. Cardiac tamponade (heart compression) is a potentially lethal condition because heart volume is increasingly compromised by the fuid outside the heart but inside the pericardial cavity. Apertures o thoracic wall: Although the thoracic cage is complete peripherally, it is open superiorly and ineriorly. The distal end o the tibia is smaller than the proximal end, faring only medially. These muscles pass between the internal suraces o adjacent ribs and occupy the lateralmost parts o the intercostal spaces. In untreated patients with transposition and intact ventricular septum, death occurs early in infancy, generally following ductal closure at a few days of age. The shape and size o the thoracic cavity and thoracic wall are dierent rom that o the chest (upper trunk or torso) because the latter includes some proximal upper limb bones and muscles and, in adult emales, the breasts. In contrast to the two deeper layers, the external oblique does not originate posteriorly rom the thoracolumbar ascia; its posteriormost bers (the thickest part o the muscle) have a ree edge where they span between its costal origin and the iliac crest.

The combination o all these movements moves the thoracic cage anteriorly, superiorly, and laterally. Given the extent o the peritoneal suraces and the rapid absorption o material, including bacterial toxins, rom the peritoneal cavity, when a peritonitis becomes generalized (widespread in the peritoneal cavity), the condition is dangerous and perhaps lethal. As coronary atherosclerosis progresses, the collateral channels connecting one coronary artery with the other expand, which may initially permit adequate perusion o the heart during relative inactivity. Lymphatic drainage rom the intermediate and proximal parts o the urethra and cavernous bodies drains into the internal iliac lymph nodes, whereas most vessels rom the distal spongy urethra and glans penis pass to the deep inguinal nodes, but some lymph passes to the external inguinal nodes. The cuboid can be elt on the lateral aspect o the oot, posterior to the base o the 5th metatarsal. If there is any doubt as to the exact location of the aortic valve, it is helpful to infuse cardioplegia solution briefly. However, the inerior articular processes o the L5 vertebra bear weight even in the erect posture. The shats o the tibia and bula are connected by a dense interosseous membrane composed o strong oblique bers descending rom the tibia to the bula. The transverse processes o thoracic and lumbar vertebrae are covered with thick muscles and may or may not be palpable. Earlier placement of the vent introduces risks of air embolism and inadequate perfusion because arterial inflow will simply return to the pump from the vent. However, if the child is not gaining weight and is suffering from frequent respiratory infections, consideration should be given to attempting balloon dilation of the valve. Other arteries involved are recurrent branches, sometimes double, rom the radial, ulnar, and interosseous arteries, which run superiorly anterior and posterior to the elbow joint. Hepatic Lobectomies and Segmentectomy When it was discovered that the right and let hepatic arteries and ducts, as well as branches o the right and let hepatic portal veins, do not communicate, it became possible to perorm hepatic lobectomies, removal o the right or let (part o the) liver, without excessive bleeding. Both serratus muscles are innervated by intercostal nerves, the superior by the rst our intercostals and the inerior by the last our. The pattern o the branches o the arch o the aorta is atypical in approximately 35% o people. I acting normally, the muscle is prominent and can be palpated at the medial margin o the cubital ossa. The testicular artery or one o its branches anastomoses with the artery o the ductus deerens. The omentum does not degenerate, however, because o anastomoses with other arteries, such as the omental branches o the let gastro-omental artery, which are still intact. The mechanical arrangement o the joints and muscles are such that a minimum o muscular activity is required to keep rom alling. The apex o the bladder points toward the superior edge o the pubic symphysis when the bladder is empty. Thin parts o the bone provide a broad surace or attachment o powerul muscles that move the emur. Except or the inerior part o the pancreatic head (including uncinate process), the spleen and pancreas receive blood rom the celiac artery. Indeed, when extrinsic muscles are also considered, the thumb has eight muscles producing and controlling the wide array o movements that distinguish the human hand. Around the middle o the arm, it pierces the medial intermuscular septum with the superior ulnar Arm 209 collateral artery and descends between the septum and the medial head o the triceps. Recurrence occurred in 25% of the patients who had resection alone but only in 4% in patients who had an adjunctive myectomy. Oten the intracapsular part o the tendon o the long head o the biceps brachii becomes rayed (even worn away), leaving it adherent to the intertubercular sulcus. In the past, the following associated anomalies have been considered contraindications, but there is no good evidence to support such an approach. It then passes close to the lateral part o the ornix o the vagina and enters the posterosuperior angle o the bladder. Postnatally, the umbilical arteries become occluded distal to the origin o the superior vesical arteries and, in the male, the arteries to the ductus deerens.

Common sites o hematogenous metastases (spreading through the blood) o cancer cells rom a bronchogenic carcinoma are the brain, bones, lungs, and suprarenal glands. The linea alba and anterior layers o the rectus sheaths are transected and resected superiorly, and the rectus muscles are retracted laterally or divided through their tendinous parts allowing reattachment without muscle ber injury. The suture technique should gather the patch a little (wider bites on the patch than on the neopulmonary artery) to create slightly bulging sinuses of Valsalva. At the root o the neck, it enters the junction o the right internal jugular and right subclavian veins, the right venous angle. The broad ligament o the uterus is a double layer o peritoneum (mesentery) that extends rom the sides o the uterus to the lateral walls and foor o the pelvis. In addition, pullback of the line into the right ventricle on the first postoperative day quantitates any residual right ventricular outflow tract gradient. The interspinales, intertransversarii, and levatores costarum are minor deep back muscles that are relatively sparse in the thoracic region. In these circumstances, the annulus is supplemented by the mitral valve component of the homograft. Oten, students ignore the variations or inadvertently damage them by attempting to produce conormity. Eerent vessels rom these nodes orm the intestinal lymphatic trunks, which may be single or multiple, and participate in the confuence o lymphatic trunks that gives rise to the thoracic duct. Two sagittally oriented ssures, linked centrally by the transverse porta hepatis, orm the letter H on the visceral surace. Hence, morphological changes in the carina are important diagnostic signs to bronchoscopists in assisting with the dierential diagnosis o respiratory disease. Impact of anatomic closure on somatic growth among small, asymptomatic children with secundum atrial septal defect. The main arteries supplying the bladder are branches o the internal iliac arteries (see Table 6. The uid-flled subarachnoid space is lined with the pia and arachnoid mater, which are continuous membranes (leptomeninges). The vaginal veins orm vaginal venous plexuses along the sides o the vagina and within the vaginal mucosa. In addition, contractions o the bladder musculature act as a sphincter preventing the refux o urine into the ureters when the bladder contracts, increasing internal pressure during micturition. Combined terms describe intermediate positional arrangements: ineromedial means nearer to the eet and median plane-or example, the anterior parts o the ribs run ineromedially; superolateral means nearer to the head and arther rom the median plane. Thoracentesis Sometimes it is necessary to insert a hypodermic needle through an intercostal space into the pleural cavity (thoracentesis) to obtain a sample o fuid or to remove blood or pus. Visceral reerred pain is transmitted by visceral aerent bers accompanying sympathetic bers and is typically reerred to somatic structures or areas such as a limb having aerent bers with cell bodies in the same spinal ganglion and central processes that enter the spinal cord through the same posterior roots (Natel, 2013). Neurovascular structures pass to and rom the neck/thorax and the entire upper limb (including the pectoral, scapular, and subscapular regions as well as the ree upper limb) via the axilla. In addition, diastolic flattening of the ventricular septum suggests an important volume overload of the right heart. Bones o oot: the many bones o the oot orm a unctional unit that allows weight to be distributed to a wide platorm to maintain balance when standing, enable conormation and adjustment to terrain variations, and perorm shock absorption. Some lymph also passes to the deep inguinal lymph nodes, located under the deep ascia on the medial aspect o the emoral vein. In adolescents and young adults, the three parts are connected together by cartilaginous joints (synchondroses) that ossiy during middle to late adulthood. Comparison of surgical and transcatheter treatment for native coarctation of the aorta in patients 1 year old. The dermatome pattern o the lower limb according to Keegan and Garrett (1948) is preerred by others or its aesthetic uniormity and obvious correlation with development. The deep bronchopulmonary lymphatic plexus is located in the submucosa o the bronchi and in the peribronchial connective tissue.

Initially, Castaneda and Norwood believed that there were several rare coronary branching patterns that were unsuitable for translocation and recommended that these children should have a Senning procedure. The veins that drain the spinal cord, as well as internal vertebral venous plexuses, drain into the intervertebral veins, which in turn drain into segmental veins. This dissection exposes the pericardial sac posterior to the body o the sternum rom just superior to the sternal angle to the level o the xiphisternal joint. Gross took up the challenge of pioneering the surgical correction of coarctation of the aorta. The membrane and the ischiopubic rami to which it attaches provide a oundation or the erectile bodies o the external genitalia-the penis and scrotum o males and the pudendum or vulva o emales-which are the supercial eatures o the triangle. Posterolateral to this part o the urethra are the small bulbo-urethral glands and their slender ducts, which open into the proximal part o the spongy urethra in the bulb o the penis. Thus, for this anomaly, early diagnosis alone should not be an automatic indication to proceed to surgery, as there is a reasonable probability that the asymptomatic patient will have relatively normal biventricular function for many years. Testicular veins traverse the greater pelvis as they pass rom the deep inguinal ring toward their posterior abdominal terminations but do not usually drain pelvic structures. In cases of severe concentric hypertrophy failure of coronary arterial bed neovascularization to keep pace with muscular hypertrophy will result in subendocardial ischemia and a predisposition to sudden death from ventricular fibrillation. The uterus can be externally manipulated to acilitate visualization, or additional openings (ports) can be made to introduce other instruments or manipulation or to enable therapeutic procedures. The ischiocavernosus and bulbospongiosus muscles both constrict venous outow rom the erectile bodies to assist erection, simultaneously pushing blood rom the penile root into the penile body. Lumbar Spinal Stenosis Lumbar spinal stenosis describes a stenotic (narrow) vertebral oramen in one or more lumbar vertebrae. This gap in the thick back musculature is a good place to examine posterior segments o the lungs with a stethoscope in a heavily muscled individual. Rupture o the pancreas requently tears its duct system, allowing pancreatic juice to enter the parenchyma o the gland and to invade adjacent tissues. The parasympathetic nerve supply is rom the pelvic splanchnic nerves via the inerior hypogastric (pelvic) plexus and nerves, which ascend retroperitoneally rom the plexus, mostly independent o the arterial supply to this part o the gastrointestinal tract. Spinal Cord the spinal cord is the major refex center and conduction pathway between the body and brain. Consequently, it enjoys protection rom the lower thoracic cage and moves with respiratory excursions. The medial surace o the medial condyle has a larger and more prominent medial epicondyle, superior to which another elevation, the adductor tubercle, orms in relation to a tendon attachment. The distal palmar crease begins at or near the clet between the index and middle ngers; it crosses the palm with a slight convexity, supercial to the head o the 3rd metacarpal and then proximal to the heads o the 4th and 5th metacarpals. Coronary sinus effluent will drain through the unroofed segment of coronary sinus into the left atrium, but this results in an acceptable small right to left shunt. Pleural eusions accumulating here do not allow the inerior margin to descend into the recess, and the usual radiolucent air density here is replaced with a hazy radiopacity. Generally, i its lower edge can be detected when palpating below the let costal margin at the end o inspiration. Wrist Fractures and Dislocations Fracture o the distal end o the radius (Colles racture), the most common racture in people >50 years o age, is discussed in the clinical box "Fractures o Radius and Ulna. The hepatic portal vein traverses the hepatoduodenal ligament (ree edge o lesser omentum and anterior boundary o omental oramen) as part o an extrahepatic portal triad (hepatic portal vein, hepatic artery, bile duct). Most o the right psoas major has been removed to show that the lumbar plexus o nerves is ormed by the anterior rami o the frst our lumbar spinal nerves and that it lies in the substance o the psoas major. Some o it is an extremely loose areolar (atty) tissue, relatively devoid o all but minor lymphatics and nutrient vessels. Because the superior part o the duodenum closely relates to the liver, gallbladder, and pancreas, any o these structures may become adherent to the infamed duodenum. Within the mesentery, the lymph passes sequentially through three groups o lymph nodes. Hyaline cartilage "end plates" cover the superior and inerior suraces o the bodies, surrounded by smooth bony epiphysial rims.

The iliopsoas is also a postural muscle, active during standing in maintaining normal lumbar lordosis (and indirectly the compensatory thoracic kyphosis; see Chapter 2, Back) and resisting hyperextension o the hip joint. Breast hypertrophy in males ater puberty (gynecomastia) is relatively rare (<1%) and may be age or drug related. The lumbar and pelvic splanchnic nerves and hypogastric plexuses have been retracted laterally or clarity. In prepubertal emales, the connective tissue capsule (tunica albuginea o the ovary) comprising the surace o the ovary is covered by a smooth layer o ovarian mesothelium or surace (germinal) epithelium, a single layer o cuboidal cells that gives the surace a dull, grayish appearance, contrasting with the shiny surace o the adjacent peritoneal mesovarium with which it is continuous. An annuloplasty ring is inserted in older patients to decrease further the diameter of the dilated tricuspid annulus, thereby improving leaflet apposition and, therefore, competence of the valve. The echocardiographer should have made a note in their report regarding the usual connection of a superior and inferior right pulmonary vein entering the left atrium. Being able to identiy normal structures on radiographs (X-rays) makes it easier to recognize the changes caused by disease and injury. The pain passes inero-anteriorly "rom the loin to the groin" as the stone progresses through the ureter. The attachments, nerve supply, and main actions o these muscles are summarized in Table 5. In the posterior mediastinum, it lies on the anterior aspect o the bodies o the inerior 7 thoracic vertebrae. The abdominopelvic splanchnic nerves include the: Lower thoracic splanchnic nerves (greater, lesser, and least): rom the thoracic part o the sympathetic trunks. It is separated rom the internal surace o the thoracic wall (sternum, ribs and costal cartilages, intercostal muscles and membranes, and sides o thoracic vertebrae) by endothoracic ascia. The one diameter that remains unaected is the true (obstetrical) diameter between the sacral promontory and the posterosuperior aspect o the pubic symphysis. Inferior vena cava Planes of: Umbilical fissure Main portal fissure Right sagittal fissure Variations in Relationships o Hepatic Arteries In most people, the right hepatic artery crosses anterior to the hepatic portal vein. Segmental medullary arteries replace the radicular arteries at the irregular levels at which they occur. The hook o the hamate can be palpated on deep pressure over the medial side o the palm, approximately 2 cm distal and lateral to the pisiorm. Anteriorly by the bodies o the pubic bones, inerior to the origin o the puborectalis. In inants and children, each hip bone consists o three separate bones united by a triradiate cartilage at the acetabulum, the cup-like depression in the lateral surace o the hip bone that articulates with the head o the emur. Details o the disposition o the aponeurotic and ascial layers o the posterior abdominal wall. The tips o the thoracic spinous processes do not indicate the level o the corresponding vertebral bodies because they overlap (lie at the level o) the vertebra below. The point at which the uterine artery and ureter cross lies approximately 2 cm superior to the ischial spine. Regarding pain rom and the treatment o hemorrhoids, it is important to note that the anal canal superior to the pectinate line is visceral; thus, it is innervated by visceral aerent pain bers, so that an incision or needle insertion in this region is painless. The epididymis is ormed by minute convolutions o the duct o the epididymis, so tightly compacted that they appear solid. The site that is selected is simply the point at the same level as the original coronary ostium with a minimal degree of rotation of the coronary. Supination is the movement o the orearm that rotates the radius laterally around its longitudinal axis, so that the dorsum o the hand aces posteriorly and the palm aces anteriorly. It crosses the let surace o the arch o the aorta anterior to the let vagus nerve and passes over the let superior intercostal vein. The lateral and medial margins o the patellar surace can be palpated when the leg is fexed. In this deep dissection, the eshy portion o the external oblique is excised on the right side, but its aponeurosis and the anterior wall o the rectus sheath are intact. Although the valve is structurally normal and of adequate size for a normal cardiac output, it is not able to carry the increased pulmonary blood flow secondary to the left to right shunt without a gradient developing. Where skin ligaments are longer and sparse, the skin is more mobile, such as on the back o the hand. Pain in all o these latter instances is conveyed initially by the meningeal branches o the spinal nerves.

The two main nerves arising rom the sacral plexus, the sciatic and pudendal nerves, lie external to the parietal pelvic ascia. The inferior epigastric artery arises rom the external iliac artery just superior to the inguinal ligament. Because the aorta lies anterior to the pulmonary artery the superior mediastinum appears narrow. These muscles appear to have a weak expiratory unction and may also provide proprioceptive inormation. This painul condition may occur in young persons during traumatic separation o the proximal epiphysis o the humerus. Thereore, single nerve injuries typically weaken, but do not eliminate, most movements. Obstruction o the biliary tract, usually the common bile duct or ampulla, results in the retention o bile pigments, enlargement o the gallbladder, and obstructive jaundice. Surace anatomy o the spleen and pancreas relative to the diaphragm and posterior abdominal viscera. The humeral head can be palpated when the arm is moved while the inerior angle o the scapula is held in place. The superior two thirds o the fgure demonstrates the suspensory ligaments and alveoli o the breast with resting lobules o mammary gland; the inerior part shows lactating lobules o mammary gland. The thin, broad membranous bands o the radiate sternocostal ligaments pass rom the costal cartilages to the anterior and posterior suraces o the sternum-is shown on the upper right side. It is likely (but undetermined) that their actions are the same as those o the internal intercostal muscles. The tendons o the muscles (represented by three fngers and the thumb) blend with the fbrous layer o the capsule o the shoulder joint to orm a musculotendinous rotator cu, which reinorces the capsule on three sides (anteriorly, superiorly, and posteriorly) as it provides active support or the joint. Here, it crosses to the right, posterior to the aorta, thoracic duct, and esophagus, and joins the azygos vein. It is important to remember that because the original aortic valve lies on a subaortic conus it is more distally placed than the neoaortic valve. The arrows indicate transient narrowing o the lumina o the ureters resulting rom peristaltic contraction. Functionally and morphologically, the bone consists o highly modifed superior and inerior ends and an intervening cylindrical shat. By allowing only slight upward movement o the inerior end o the sacrum relative to the hip bones, resilience is provided to the sacroiliac region when the vertebral column sustains sudden increases in orce or weight. This commissure of the neopulmonary valve will need to be detached in order to harvest a button that contains the full length of the intramural coronary artery. On each side, the pubic bones and ascia covering the levator ani and superior obturator internus muscle lie in contact with the inerolateral suraces o the bladder. Patients with sternal contusion should be evaluated or underlying visceral injury (Marx et al. Because arterial pressure is much higher in the systemic than in the pulmonary circulation, the let ventricle perorms more work than the right ventricle. The interior o the descending part o the duodenum reveals the major and minor duodenal papillae. Medial to the iliopectineal arch, the vascular compartment o the retro-inguinal space allows passage o the major vascular structures (veins, artery, and lymphatics) between the greater pelvis and the emoral triangle o the anterior thigh. The trabecular bone is a meshwork o mostly tall vertical trabeculae intersecting with short, horizontal trabeculae. Ultrasound is a noninvasive means o distinguishing fuid-lled cysts or abscesses rom solid masses. The anal triangle lies posterior Lymphatic vessels rom the ovaries, joined by vessels rom the uterine tubes and most rom the undus o the uterus, ollow the ovarian veins as they ascend to the right and let lumbar (caval/aortic) lymph nodes. The basin-like nature or which the pelvis was named is evident in this coronal section. Presumably this results from the greater degree of retraction of the tricuspid annulus that is required for this approach.

The ourth muscle o the layer (the exor carpi ulnaris) has been retracted medially. During its course through the arm, the brachial artery gives rise to many unnamed muscular branches, and the humeral nutrient artery. The coronary buttons are sutured into the neoaorta using continuous 7/0 Prolene and very small needles. Regional study o deep structures and abnormalities in a living person is now also possible by means o radiographic and sectional imaging and endoscopy. It is important thereore to know that the emoral vein has no tributaries at this level, except or the great saphenous vein that joins it approximately 3 cm inerior to the inguinal ligament. By themselves, the anterior and posterior spinal arteries can supply only the short superior part o the spinal cord. The lateral sacral arteries pass medially and descend anterior to the sacral anterior rami, giving o spinal branches, which pass through the anterior sacral oramina and supply the spinal meninges enclosing the roots o the sacral nerves. Small veins are the tributaries o larger veins that unite to orm venous plexuses (networks o veins), such as the dorsal venous arch o the oot. Peritoneal dialysis may be perormed in which soluble substances and excess water are removed rom the system by transer across the peritoneum, using a dilute sterile solution that is introduced into the peritoneal cavity on one side and then drained rom the other side. In emales, as the peritoneum at or near the midline reaches the posterior border o the roo o the bladder, it refects onto the anterior aspect o the uterus at the isthmus o the uterus (see "Female Internal Genital Organs"); thus, it is not related to the anterior vaginal ornix, which is subperitoneal in location. The emur is "bent" so that the long axis o the head and neck lies at an angle (angle o inclination) to that o the shat. The superfcial lymphatic vessels converge toward and accompany the great saphenous vein, draining into the inerior (vertical) group o superfcial inguinal lymph nodes. Proximal gastric vagotomy denervated the stomach but the vagal branches to the pylorus, liver and biliary ducts, intestines, and celiac plexus were preserved. The lymphatic vessels o the gallbladder and biliary passages anastomose superiorly with those o the liver and ineriorly with those o the pancreas; most drainage ows to the celiac lymph nodes. In most patients, a right atriotomy procedure alone was used, although an apical left ventriculotomy was used for apical defects. Afterload reduction is particularly helpful in the setting of mitral regurgitation and should be maximized. The glenohumeral ligaments are three brous bands, evident only on the internal aspect o the capsule, that reinorce the anterior part o the joint capsule. Their proximal stumps begin to regenerate, sending sprouts into the area o the lesion; however, this growth is blocked by astrocyte prolieration at the injury site, and the axonal sprouts are soon retracted. The ovaries and uterine tubes receive a double (collateral) blood supply rom the abdominal aorta via the ovarian arteries and rom the internal iliac arteries via the uterine arteries. Colostrum, a creamy white to yellowish premilk fuid, may secrete rom the nipples during the last trimester o pregnancy and during initial episodes o nursing. The proximal part has the hepatoduodenal ligament (part o the lesser omentum) attached superiorly and the greater omentum attached ineriorly. Ninety-three % of patients were in New York Heart Association class 1 or 2 at more than 1 year following surgery. The pulpy nucleus attens and the anulus bulges when weight is applied, as occurs during standing and more so during liting. Between it and the distal part o the coronoid process is a concavity, the supinator ossa. External spermatic ascia: derived rom the external oblique aponeurosis and its investing ascia. When measuring the upper limb, or segments o it, or comparison with the contralateral limb, or with standards or normal limb growth or size, the acromial angle. Colonoscopy, Sigmoidoscopy, and Colorectal Cancer the interior o the colon can be observed and photographed in a procedure called colonoscopy or coloscopy, using a long, fexible beroptic endoscope (colonoscope) inserted into the colon through the anus and rectum. The risk of recurrence is not low and is higher in children under 10 years of age. In some cases, the main pancreatic duct is smaller than the accessory pancreatic duct and the two may not be connected. However, they also serve as accessory respiratory muscles by xing these ribs and enabling the muscles connecting the ribs below to be more eective in elevating the lower ribs during orced inspiration. This motion initially ejects the blood rom the ventricles as the outer (basal) spiral contracts, rst narrowing and then shortening the heart, reducing the volume o the ventricular chambers.

Immediately distal and at a deeper level to the latter, the antebrachial ascia is also continued as the exor retinaculum (transverse carpal ligament). The ngers o the relaxed hand also remain in the fexed position at the metacarpophalangeal joints. To be understood, you must express yoursel clearly, using the proper terms in the correct way. The body o the ischium helps orm the acetabulum and the ramus o the ischium orms part o the obturator oramen. Retrograde flow in the left main, as well as evidence of papillary muscle fibrosis, may alert the echocardiographer to the presence of this exceedingly rare problem. The special arrangements o the anterolateral abdominal muscles enable them to provide exible containing walls or the abdominal contents, to increase intra-abdominal pressure or decrease abdominal volume or expulsion, and to produce anterior and lateral exion and torsional (rotatory) movements o the trunk. A transverse line joining the anterior ends o the ischial tuberosities divides the diamond-shaped perineum into two triangles, the oblique planes o which intersect at the transverse line. Both maps are approximations, delineating dermatomes as distinct zones when actually there is much overlap between adjacent dermatomes and much variation (even rom side to side in the same individual). This results in fibrous continuity between the pulmonary and mitral valves, a hallmark of transposition. It has many causes, all o which result in a reduced blood supply to the vital myocardial tissue. The venous drainage rom the submucosal veins o this part o the esophagus is both to the portal venous system through the let gastric vein. Sometimes a peroration (sternal oramen) remains in the sternal body because o incomplete usion. Ater this early embryonic period, our segmental structure is most evident in the skeleton (vertebrae and ribs) and nerves and muscles o the thoracic region. Because the sacral hiatus is located between the sacral cornua and inerior to the S4 spinous process or median sacral crest, these palpable bony landmarks are important or locating the hiatus. A asciotomy (incision o overlying ascia or a septum) may be perormed to relieve the pressure in the compartment(s) concerned. These branches are usually represented by slender nerves, but the communications are important clinically because even with a complete lesion o the median nerve, some muscles may not be paralyzed. The connective tissue is pierced by numerous openings (thus its name) or the passage o eerent lymphatic vessels rom the supercial inguinal lymph nodes and by the great saphenous vein and its tributaries. The papilla probably serves as a relatively passive fap valve, preventing refux rom the cecum into the ileum as contractions occur to propel contents up the ascending colon and into the transverse colon (Magee and Dalley, 1986). Deep palpation o the midabdomen can detect an aneurysm, which usually results rom a congenital or acquired weakness o the arterial wall. The convex posterior surace o the scapula is unevenly divided by a thick projecting ridge o 1 the scapulothoracic joint is a physiological "joint," in which movement occurs between musculoskeletal structures (between the scapula and associated muscles and the thoracic wall), rather than an anatomical joint, in which movement occurs between directly articulating skeletal elements. Deep lymphatic vessels accompany deep veins o the abdominal wall to the iliac and right and let lumbar (caval and aortic) lymph nodes. An embolus in a pulmonary artery orms when a blood clot, at globule, or air bubble travels in the blood to the lungs rom a leg vein, or example, ater a compound racture. I necessary, traction o the ureters is applied gently and only toward the blood supply to avoid disruption o the small branches. It normally contains a thin lm o fuid that enables the heart to move and beat in a rictionless environment. The cervical pleura is reinorced by a brous extension o the endothoracic ascia, the suprapleural (continued on p. Anatomicomedical Terminology 7 * Superficial Nearer to surface the muscles of the arm are superficial to its bone (humerus). While most movements occur at joints where two or more bones or cartilages articulate with one another, several nonarticulated structures exhibit movement.
