Assistant Professor, New York University School of Medicine Here, it again splits to enclose this organ, reforms at its greater curve, then loops downwards and then up again to attach to the length of the transverse colon, forming the apron-like greater omentum man health about inguinal hernia men purchase eulexin 250 mg. The transverse colon, in turn, is enclosed within this peritoneum, which then passes upwards and backwards as the transverse mesocolon to the posterior abdominal wall, where it is attached along the anterior aspect of the pancreas. At the base of the transverse mesocolon, this double peritoneal sheet divides once again; the upper leaf passes upwards over the posterior abdominal wall to reflect onto the liver (at the bare area), the lower leaf passes over the lower part of the posterior abdominal wall to cover the pelvic viscera and to link up once again with the peritoneum of the anterior wall. This posterior layer is, however, interrupted by its being reflected along an oblique line running from the duodenojejunal flexure, above and to the left, to the ileocaecal junction, below and to the right, to form the mesentery of the small intestine. The mesentery of the small intestine, the lesser and greater omenta and mesocolon all carry the vascular supply and lymph drainage of their contained viscera. Its left wall is formed by the spleen attached by the gastrosplenic and splenorenal (lienorenal) ligaments. The right extremity of the sac opens into the main peritoneal cavity via the epiploic foramen or foramen of Winslow. Notice that none of these important boundaries can be incised to release the strangulation; the bowel must be decompressed by a needle to allow its reduction. If the cystic artery is torn during cholecystectomy, haemorrhage can be controlled by this manoeuvre (named after James Pringle), which then enables the damaged vessel to be identified and secured. Intraperitoneal fossae A number of fossae occur within the peritoneal cavity in which loops of bowel may become caught and strangulated. One or more of these spaces may become filled with pus (a subphrenic abscess) walled off inferiorly by adhesions. The right and left subphrenic spaces lie between the diaphragm and the liver, separated from each other by the falciform ligament. The right is the pouch of Morison and is bounded by the posterior abdominal wall behind and by the liver above. It communicates anteriorly with the right subphrenic space around the anterior margin of the right lobe of the liver and below both open into the general peritoneal cavity from which infection the gastrointestinal tract 77 may track, for example, from a perforated appendix or a perforated peptic ulcer. The left subhepatic space is the lesser sac, which communicates with the right through the foramen of Winslow. It may fill with fluid as a result of a perforation in the posterior wall of the stomach or from an inflamed or injured pancreas to form a pseudocyst of the pancreas. The right extraperitoneal space lies between the bare area of the liver and the diaphragm. It may become involved in retroperitoneal infections or directly from a liver abscess. Posterior subphrenic abscesses are drained by an incision below, or through the bed of, the 12th rib. A finger is then passed upwards and forwards between the liver and diaphragm to open into the abscess cavity. An anteriorly placed collection of pus below the diaphragm can alternatively be drained via an incision placed below and parallel to the costal margin. The gastrointestinal tract the stomach the stomach is roughly J-shaped, although its size and shape vary considerably. It tends to be high and transverse in the obese short subject and to be elongated in the asthenic individual; even in the same person, its shape depends on whether it is full or empty, on the position of the body and on the phase of respiration. The stomach projects to the left, above the level of the cardiac orifice (or cardia), to form the dome-like gastric fundus. Between the cardiac orifice and the incisura is the body of the stomach, while the area between the incisura and the pylorus is the pyloric antrum. The junction of the pylorus with the duodenum is marked by a constriction externally and also by a constant vein that crosses it, the vein of Mayo. The thickened pyloric sphincter is easily felt and surrounds the lumen of the pyloric canal. The pyloric sphincter is an anatomical structure as well as a physiological mechanism. The cardia, on the other hand, although competent (gastric contents do not flow out of your mouth if you stand on your head), is not demarcated by a distinct anatomical sphincter. The exact nature of the cardiac sphincter action is still not fully understood, but the following mechanisms have been suggested, each supported by some experimental and clinical evidence. The lesser omentum is attached along the lesser curvature of the stomach; the greater omentum along the greater curvature. Syndromes
When defecation is desired, on the other hand, adopting a sitting or squatting position changes the relative orientation of the intestine and surrounding muscular structures to straighten the pathway for fecal exit prostate cancer journal articles cheap eulexin 250 mg overnight delivery. This is also assisted by relaxation of the puborectalis muscle, which results in a less acute rectoanal angle. Rectal contraction then produces the propulsive force to move the feces out of the body. Evacuation is enhanced by simultaneous contraction of the rectus abdominus, diaphragm, and other levator ani muscles, which increases intra-abdominal pressure. All of these events occur whether solid (in health) or liquid (in disease) feces are expelled, although less force is obviously needed to evacuate liquid feces. On the other hand, the voluntary expulsion of flatus involves the contractile functions listed, but the puborectalis muscle does not relax and there is no change in the rectoanal angle. This allows the flatus gas to be forced past the acutely angled anorectum without the simultaneous loss of feces. He later regurgitates a bedtime snack and complains of a feeling that the pill "did not go all the way down," so is taken to the emergency room. On physical examination, he is found to be somewhat underweight, agitated, and clearly distressed. The aide that accompanied him reports that this situation has occurred previously. A gastroenterologist is called and performs an upper endoscopy, whereupon the pill can be seen lodged in the mid-esophagus. The gastroenterologist advises the nursing home aide that the patient should be given only semisolid food in future, and that any needed pills should be crushed and mixed with apple sauce to administer them to the patient. Difficulty in swallowing is referred to as dysphagia, and can result from abnormalities in any of the components of the swallowing reflex or the anatomic structures involved. For example, abnormalities of the tongue can result in dysphagia because the bolus cannot be propelled backward toward the pharynx with sufficient force. In general, dysphagia can be considered as arising from either the oropharynx and striated muscle region of the esophagus or the smooth muscle portion of the esophagus, corresponding to the different innervation and mechanisms of sensation and control in these two areas. Dysphagia is a common medical problem that is especially frequent in the elderly, and associated with much distress, as well as the risk of aspiration, choking, and malnutrition. It is estimated that up to 13% of hospitalized patients and as many as 60% of nursing home residents have feeding problems, most of which are the result of oropharyngeal dysphagia. All patients with dysphagia will experience problems with solid food, and may have varying degrees of difficulty swallowing liquids as well, depending on the severity of the underlying cause. Structural causes of dysphagia extend to diverticula, or outpouchings of the pharyngeal or esophageal wall in which food can become trapped, or to various forms of obstruction. The latter include mucosal or muscular rings that circumferentially occlude a portion of the esophageal lumen. Functional causes of dysphagia relate to either neurological control of the oropharyngeal phase of swallowing, peristalsis, and esophageal sphincter relaxation or defects in the muscle layers themselves. When there are structural abnormalities, surgery to repair diverticula, cut overly tight muscles, or remove an obstructing tumor can often bring some relief. Mechanical dilation of a stricture (abnormal narrowing) is also attempted, with varying degrees of success. In the case of functional disorders, on the other hand, effective therapy usually depends on whether treatment is available for the underlying disorder, and surgery is much less helpful. Swallowing is initiated voluntarily, but thereafter reflects a complex integration of regulatory influences coordinated by the swallowing center in the brain. Two sphincters, normally closed, regulate the movement of the bolus into and out of the esophagus. The stomach serves to receive the meal from the esophagus, and it displays motility functions that both initiate the process of digestion and control the delivery of nutrients to more distal segments. Receptive relaxation of the proximal stomach allows the stomach to function as a reservoir and ensures that the pressure within the stomach changes little as its volume expands to receive the meal. The distal stomach uses phasic contractions to grind the meal, moving only the smallest particles to the pylorus. Emptying of the stomach involves tonic contractions of the proximal portions, and depends on both the physical and chemical characteristics of the meal. Nutrients and the osmolarity of the meal feed back to retard gastric emptying once they reach the small intestine via both neural and humoral mechanisms. It is made up of the right and left cerebellar the brain 369 hemispheres and a median vermis prostate cancer 83 year old man eulexin 250 mg sale. Inferiorly, the vermis is clearly separated from the two hemispheres and lies at the bottom of a deep cleft, the vallecula; superiorly, it is marked off from the hemispheres only as a low median elevation. A small ventral portion of each cerebellar hemisphere lies on the middle cerebellar peduncle of its side, and is almost completely separated from the rest of the cerebellum. The surface of the cerebellum is divided into numerous narrow folia and, by a few deep fissures, into a number of lobules. The effect of this fissuring is to give the cerebellum in section the appearance of a many-branched tree (the arbor vitae). It consists of a cortex of grey matter (in which all the afferent fibres terminate) covering a mass of white matter, in which deep nuclei of grey matter are buried. The cerebellum is connected to the brainstem by way of three pairs of cerebellar peduncles. The inferior peduncles connect it to the dorsolateral aspect of the medulla; the middle cerebellar peduncles to the pons; and the superior peduncles to the caudal midbrain. Ventrally, the cerebellum is related to the 4th ventricle and to the medulla and pons; laterally, to the sigmoid venous sinus and the mastoid antrum and air cells; and posterosuperiorly, it is separated from the cerebral hemispheres by the tentorium cerebelli. Functions of the cerebellum the principal function of the cerebellum is to regulate and maintain balance, and to co-ordinate timing and precision of body movements. The cerebellum has multiple connections with the cerebral cortex, reticular formation in the brainstem, thalamus and vestibular nuclei. Through these intricate connections, the cerebellum constantly monitors proprioceptive sensory input from joints, muscles and tendons, and accordingly refines and co-ordinates the contractions of skeletal muscles. However, unlike the cerebral cortex of the primary motor area, the cerebellum is incapable of initiating movement, nor is the cerebellum involved in the conscious perception of somatic or visceral sensations. Lesions of the cerebellum give rise to symptoms and signs on the same side of the body. Destruction of the dentate nucleus (a large collection of cells within the cerebellar white matter) or the superior cerebellar peduncle results in a disability almost as severe as ablation of the entire cerebellar hemisphere. The diencephalon the diencephalon comprises principally the hypothalamus and thalamus, which are continuous with each other. A vertically disposed, median, cleftlike space is present between the right and left halves of the diencephalon, and is called the 3rd ventricle. In addition to the thalamus and hypothalamus, the diencephalon includes two small but functionally important regions: the epithalamus and ventral thalamus. The epithalamus is the dorsal portion of the diencephalon and contains the pineal body. The ventral thalamus (also known as the subthalamus) contains the subthalamic nucleus, which is one of the basal ganglia. It is believed to be the main regulator and modulator of the other basal ganglia, and thus is a significant influence on motor activity. Viewed from below, the hypothalamus is seen to include, from before backwards, the optic chiasma, the tuber cinereum, the infundibular stalk (leading down to the posterior lobe of the pituitary), the mamillary bodies and the posterior perforated substance. Sherrington described the hypothalamus as the head ganglion of the autonomic system. It is largely concerned with autonomic activity and can be divided into a posteromedial sympathetic area and an anterolateral area concerned with parasympathetic activity. The hypothalamus plays an important role in endocrine control by the formation of releasing factors or release-inhibiting factors. These substances, following their secretion into the hypophyseal portal vessels, influence the production by the cells of the anterior pituitary of adrenocorticotrophin, follicle-stimulating hormone, luteinizing hormone, prolactin, somatotrophin, thyrotrophin and melanocyte-stimulating hormone. The hormones oxytocin and vasopressin (antidiuretic hormone) are produced by two distinct aggregations of neurones (the paraventricular and supra-optic nuclei, respectively) in the hypothalamus and released at their axon terminals in the posterior pituitary. Laterally, it is related to the internal capsule (and through it to the basal ganglia), and dorsally to the floor of the lateral ventricle. Medially, it is frequently connected with its fellow of the opposite side through the massa intermedia (interthalamic connexus). Posteriorly, it presents three distinct eminences, the pulvinar, and the medial and lateral geniculate bodies, the last two are the thalamic relay nuclei of hearing and vision, respectively. The thalamus is the principal sensory relay nucleus that projects impulses from the main sensory pathways onto the cerebral cortex. This ostium primum defect lies immediately above the atrioventricular boundary and may be associated with a defect of the pars membranacea septi of the ventricular septum prostate cancer active surveillance order eulexin online pills. In such a case, the child is born with both an atrial and ventricular septal defect. Occasionally, the ventricular septal defect is so huge that the ventricles form a single cavity, giving a trilocular heart. Congenital pulmonary stenosis may affect the trunk of the pulmonary artery, its valve or the infundibulum of the right ventricle. If stenosis occurs in conjunction with a septal defect, the compensatory hypertrophy of the right ventricle (developed to force blood through the pulmonary obstruction) develops a sufficiently high pressure to shunt blood through the defect into the left heart; this mixing of the deoxygenated right heart blood with the oxygenated left-sided blood results in the child being cyanosed at birth. This results from unequal division of the truncus arteriosus by the spiral septum, resulting in a stenosed pulmonary trunk and a wide aorta that overrides the orifices of both the ventricles. The displaced septum is unable to close the interventricular septum, which the mediastinum 45. Right ventricular hypertrophy develops as a consequence of the pulmonary stenosis. Cyanosis results from the shunting of large amounts of unsaturated blood from the right ventricle through the ventricular septal defect into the left ventricle and also directly into the aorta. If left uncorrected, it causes progressive work hypertrophy of the left heart and pulmonary hypertension. There may be an extensive obstruction of the aorta from the left subclavian artery to the ductus, which is widely patent and maintains the circulation to the lower parts of the body; often, there are multiple other defects and frequently infants so afflicted die at an early age. More commonly, there is a short segment involved in the region of the ligamentum arteriosum or still patent ductus. In these cases, circulation to the lower limbs is maintained via collateral arteries around the scapula anastomosing with the intercostal arteries, and via the link-up between the internal thoracic and inferior epigastric arteries. Clinically, this circulation may be manifest by enlarged vessels being palpable around the scapular margins; radiologically, dilatation of the engorged intercostal arteries results in notching of the inferior borders of the ribs. Abnormal development of the primitive aortic arches may result in the aortic arch being on the right or actually being double. The superior mediastinum this is bounded in front by the manubrium sterni and behind by the first four thoracic vertebrae. Above, it is in direct continuity with the root of the neck, and, below, it is continuous with the three subdivisions of the inferior mediastinum. Its principal contents are: the great vessels, trachea, oesophagus, thymus, thoracic duct, vagi, left recurrent laryngeal nerve and the phrenic nerves. The brachiocephalic veins lie in front of the arteries, the left running almost horizontally across the superior mediastinum and the right vertically downwards; the two unite to form the superior vena cava. Posteriorly lies the trachea with the oesophagus immediately behind it lying against the vertebral column. The thymus is a soft, bi-lobed organ that lies in the superior mediastinum, closely related to the left brachiocephalic vein, and extends downwards into the anterior part of the inferior mediastinum. The mediastinum 47 the gland is large in the fetus and young child, and may extend upwards into the neck even as far as the lower pole of the thyroid gland. It fails to increase much in size after childhood, and thus becomes comparatively smaller in the adult. Moreover, although it is pink and glandular in the fetus and child, it becomes increasingly infiltrated with fat in later years; in adults, it is distinguishable from surrounding fat only by its distinct capsule. The oesophagus the oesophagus, which is 10 in (25 cm) long, extends from the level of the lower border of the cricoid cartilage at the level of the 6th cervical vertebra to the cardiac orifice of the stomach. Thoracic duct Left recurrent laryngeal nerve Left common cartoid artery Left subclavian artery Arch of aorta Oesophagus Outline of pericardium Right crus of diaphragm. The trachea and the thyroid gland are its immediate anterior relations, the 6th and 7th cervical vertebrae and the prevertebral muscles covered by prevertebral fascia are behind it and on either side it is related to the common carotid arteries and the recurrent laryngeal nerves. On the left side it is also related to the subclavian artery and the terminal part of the thoracic duct. Thoracic the thoracic part traverses first the superior and then the posterior mediastinum.
