The teniae coli run the length of the colon. A proposed explanation for the existence of haustra is that the colon becomes sacculated between the teniae coli because the taenia coli are shorter than the colon. However, it is now more commonly accepted that the haustra form because of enteric nervous system activity. [1]
The gastrocolic reflex or gastrocolic response is a physiological reflex that controls the motility, or peristalsis, of the gastrointestinal tract following a meal. It involves an increase in motility of the colon consisting primarily of giant migrating contractions, in response to stretch in the stomach following ingestion and byproducts of digestion entering the small intestine. [1]
Segmentation contractions (or movements) are a type of intestinal motility.. Unlike peristalsis, which predominates in the esophagus, segmentation contractions occur in the large intestine and small intestine, while predominating in the latter.
The transverse colon is the part of the colon from the hepatic flexure, also known as the right colic, (the turn of the colon by the liver) to the splenic flexure also known as the left colic, (the turn of the colon by the spleen). The transverse colon hangs off the stomach, attached to it by a large fold of peritoneum called the greater omentum.
There are three teniae coli: mesocolic, free and omental taeniae coli. The teniae coli contract lengthwise to produce the haustra, the bulges in the colon. Large bowel (sigmoid colon) with multiple diverticula. These appear on either side of the longitudinal muscle bundle (taenium). The bands converge at the root of the vermiform appendix.
There is strong evidence that higher levels of physical activity reduce the risk of bladder, breast, colon, endometrial, oesophageal and stomach cancers, and some evidence that it may lower the ...
In the anatomy of the human digestive tract, there are two colic flexures, or curvatures in the transverse colon. The right colic flexure is also known as the hepatic flexure, and the left colic flexure is also known as the splenic flexure. [1] Note that "right" refers to the patient's anatomical right, which may be depicted on the left of a ...
