descending colon การใช้

• He had a number of operations, and finally his descending colon was removed.
• The lateral boundary of the retroperitoneum is defined by the ascending and descending colon.
• The cancer was located in the area of the large intestine known as the descending colon.
• These include the esophagus, pylorus of the stomach, distal duodenum, ascending colon, descending colon and anal canal.
• The "'descending colon "'is the part of the large intestine from the splenic flexure to the beginning of the sigmoid colon.
• The retroperitoneal regions include the oral cavity, esophagus, pylorus of the stomach, distal duodenum, ascending colon, descending colon and anal canal.
• The right and left paracolic gutters are peritoneal recesses on the posterior abdominal wall lying alongside the ascending and descending colon.
• Of the colon, the ascending colon, descending colon and rectum are retroperitoneal, while the cecum, appendix, transverse colon and sigmoid colon are intraperitoneal.
• The function of the descending colon in the digestive system is to store the remains of digested food that will be emptied into the rectum.
• Two-thirds of all vertex presentations are LOA, possibly because of the asymmetry created by the descending colon that is on the left side of the pelvis.
• From the S2, S3 and S4 arise the pudendal nerve and parasympathetic fibers whose electrical potential supply the descending colon and rectum, urinary bladder and genital organs.
• The "'left colic flexure "'or splenic flexure ( as it is close to the spleen ) is the sharp bend between the transverse colon and the descending colon.
• This means that even when an enema cleans the colon rather easily, stool keeps on passing fairly quickly from the cecum to the descending colon and the anus.
• It begins at the level of the iliac crest, where it is continuous with the descending colon, and ends in the sigmoid colon at the superior aperture of the lesser pelvis.
• Their branches supply the lower part of the descending colon, the iliac colon, and the sigmoid or pelvic colon; anastomosing above with the left colic, and below with the superior hemorrhoidal artery.
• The muscles of the colon then move the watery waste material forward and slowly absorb all the excess water, causing the stools to gradually solidify as they move along into the descending colon.
• Of note, the splenic flexure, or the junction between the transverse and descending colon, is supplied by the most distal portions of both the inferior mesenteric artery and superior mesenteric artery, and is thus referred to medically as a shock.
• The final branch which is important for the digestive system is the inferior mesenteric artery, which supplies the regions of the digestive tract derived from the hindgut, which includes the distal 1 / 3 of the transverse colon, descending colon, sigmoid colon, rectum, and the anus above the pectinate line.
• The mesentery associated with the ascending colon and descending colon is resorbed, bringing these parts of the colon into close contact with the body wall . " To reconcile these differences, several theories of embryologic mesenteric development including the " regression " and " sliding " theories have been proposed, but none has been widely accepted.
