Description

Three systems of vessels in succession distribute the blood to the skin after delivery by perforating arteries allergy medicine least side effects promethazine 25 mg discount. These systems are interconnected by a complex network of vessels of varying sizes. If the dermis becomes excessively deformed, the rigidity of the surrounding collagen may compromise the lumens of these vessels with resulting ischemia. It must be appreciated that the principal function of the cutaneous vasculature is not for skin nutrition but for thermoregulation and is under neural control. Hair follicles, present in most parts of the body, transfix the dermis and probably restrict its mobility. They are both eccrine (secretory) glands, some of which respond to stress and some regulate temperature, and apocrine (shedding) glands that release the apical portion of the gland, producing a secretion with a characteristic odor. After placement as a graft, the skin temporarily loses the normal lubrication from these glands and, unless protected with bland creams until glandular function returns, it becomes dry and susceptible to injury. Subcutaneous Layer the subcutaneous layer is fatty and serves principally as insulation. It contains free and encapsulated nerve endings for several types of sensory input and for control of the vascular supply. The subcutaneous tissue sends protrusions of fat, the fat domes or adipose columns, into the dermis. When the skin is cut at this level, a collagen network, which has interstices into which fat protrudes, is exposed. These extensions of elements of the skin into the subcutaneous tissue account for the reepithelialization that occurs in the donor site after split-thickness grafts are harvested or after deep burns. Strands of collagen run through the subcutaneous layer to attach the dermis to the underlying muscle. For example, over the penis, they are small and flexible; over the ilium, they are dense and firm. The skin maintains its physical characteristics on transplantation, making cosmetic matching difficult. Stress relaxation may become apparent some time after the skin has been held stretched to the limit. Tension is the result of stretch of the elastic fibers and varies from point to point about the body. The crease lines are the lines of zero tension applied perpendicular to the crease. Scars form when tension across the suture line rises above a critical level, a level that varies by site (low tension on the skin of the penis and scrotum) and with age (low tension in the skin of the elderly).

Afferent glomerular arterioles arise at all levels from the interlobular arteries "like branches from a tree allergy forecast waco tx 25 mg promethazine with amex. The peripheral arterioles take a more vertical course, appearing as continuations of the interlobular arteries. One branch supplies the convoluted tubules and the loops of Henle, and the other runs centrally as arteriae rectae to supply the collecting ducts. The latter probably results from degeneration of the glomerulus and so should not be classified separately. The venae rectae arise from this plexus and drain peripherally into the arcuate veins. Perforating capsular arteries are similar to interlobular arteries but serve few or no glomeruli. They pass to the surface of the kidney to join the capsular arterial and venous plexus, where they form a collateral circulation, the blood flowing from the kidney to the perirenal tissue. The direction of flow may become reversed in states of renal ischemia, depending on the pressure gradient. Branches enter from the pelvic arterial plexus in which the vessels along the wall of the calyx form an oval pattern. These vessels curve over the fornix as spiral arteries and turn beneath the mucosa of the papilla to join the capillary bed of the papillary plexus around the papillary ducts. They also supply the connective tissue in the fornix and around the bases of the interlobar vessels. Should the pelvic arterial plexus be damaged, as by chronic infection and diabetes or obstruction, the papilla depends on the delicate vasae rectae for vascular support. Blood Supply to the Capsule the capsular arterial and venous plexus is a distinct system of blood vessels that anastomoses with intrarenal and extrarenal sources. The capsule is supplied by three peripheral vessels that have a characteristic spiral form. A superior capsular artery, usually a branch of the adrenal artery, follows the lateral margin of the upper pole of the kidney. A middle capsular artery emerges at the hilum from the main renal artery to supply the dorsal and ventral aspects. The third is a small inferior capsular artery that arises from the gonadal artery to run along the lateral border of the kidney. Anastomoses are frequent with the lumbar, internal iliac, intercostal, and other retroperitoneal vessels. The capsular plexus is also supplied by an average of six relatively large perforating arteries that run directly from the arcuate arteries. These arteries may be an important source of collateral circulation and also may distort determinations of medullary blood flow by acting as a shunt. Blood Supply to the Pelvis and Calyces Rich pelvic arterial plexuses lie in the peripelvic connective tissue sheath of the wall of the pelvis and the major and minor calyces. They are supplied by branches from an interlobar artery that passes to the wall of a nearby calyx, where the branch becomes very tortuous, forming a spiral artery, a vessel that becomes more convoluted with age.

Although in the illustration it is represented as a separate layer allergy forecast norman ok promethazine 25 mg fast delivery, the transversus abdominis is actually fused with the overlying part of the sheath that is derived from the internal oblique. The lowest fibers of the aponeurosis attach to the lateral part of the inguinal ligament, arch over the inguinal ligament and the inguinal canal, and in combination with the internal oblique, make up a portion of the conjoined tendon. Conjoined Tendon the conjoined tendon of the internal oblique and transversus, composed principally of the aponeurosis of the latter muscle, inserts into the crest and usually to the ridge of the pubis. Serratus Anterior the serratus anterior inferior inserts on ribs 7 and 8 after emerging from beneath the latissimus dorsi. Blood Supply Besides that from the lower intercostal vessels, blood is supplied by the superior epigastric artery that lies on the posterior rectus sheath and goes to the rectus and part of the transversus abdominis. Nerve Supply the ventral rami of the lower six thoracic and the first lumbar nerves innervate the skin, muscles, and peritoneum over the anterior abdomen. Intercostal nerves 7 to 11 exit from the intercostal space to enter the neurovascular plane, lying between the internal oblique and transversus abdominis. Intercostal nerves 7 and 8 slope upward, the 9th courses horizontally, and the 10th and 11th run obliquely downward. They terminate medially as anterior cutaneous branches in the skin after passing through the rectus abdominis and anterior rectus sheath. The 12th or subcostal nerve runs forward under the 12th rib, then enters the neurovascular plane over the transversus abdominis. The six lowest intercostal nerves give off lateral cutaneous nerves that separate into an anterior branch to supply the skin up to the lateral edge of the rectus abdominis and a posterior branch to innervate the skin over the latissimus dorsi. The upper branch is the iliohypogastric nerve, which divides just above the iliac crest to form the lateral cutaneous branch to the buttock and the anterior cutaneous branch to the suprapubic region. The lower branch, the ilioinguinal nerve, after running in the neurovascular plane, goes through the internal oblique above the iliac crest to reach the spermatic cord (or the round ligament of the uterus) in the inguinal canal. Surgeons: Note that the intercostal nerves and accompanying vessels lie on the surface of the investing fascia of the transversus abdominis, as does the iliohypogastric nerve and the terminal part of the ilioinguinal nerve. These nerves run at an angle downward in the lower part of the abdomen but in the upper portion their course is obliquely upward, making denervation of the rectus possible with chevrontype incisions. The paired pyramidalis muscles, arising from the anterior surface of the symphysis pubis, insert in the linea alba inside the rectus sheath. Rectus Sheath the sheath containing each rectus abdominis is formed from combined aponeuroses of the anterior abdominal wall muscles. The anterior rectus sheath covers the muscle for its full length and is firmly attached to it at the tendinous intersections. Above the costal margin, the anterior sheath is comprised solely of the external oblique aponeurosis.
