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.
The large intestine absorbs some of the products formed by the bacteria inhabiting this region. Undigested polysaccharides (fiber) are metabolized to short-chain fatty acids by bacteria in the large intestine and absorbed by passive diffusion. The bicarbonate that the large intestine secretes helps to neutralize the increased acidity resulting ...
In the colon, for example, the muscular layer is much thicker because the faeces are large and heavy and require more force to push along. The outer longitudinal layer of the colon thins out into 3 discontinuous longitudinal bands, known as taeniae coli (bands of the colon). This is one of the 3 features helping to distinguish between the large ...
The appendages themselves are 50–100 appendages that are oriented in two rows anterior and posterior. The appendages are parallel to the superficial section of the taenia coli. Furthermore, the appendages are between 0.5 and 5 cm long, each appendage is attached with one or two arterioles and a venule within vascular stalks attached to the colon.
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]
[1] [10] Other symptoms may include fever, abdominal pain, and a feeling of incomplete defecation. [2] [6] [11] Complications may include dehydration. [3] The cause of dysentery is usually the bacteria from genus Shigella, in which case it is known as shigellosis, or the amoeba Entamoeba histolytica; then it is called amoebiasis. [1]
Taeniasis is an infection within the intestines by adult tapeworms belonging to the genus Taenia. [2] [3] There are generally no or only mild symptoms. [2]Symptoms may occasionally include weight loss or abdominal pain. [1]
Taenia coli, three separate longitudinal ribbons of smooth muscle of the large intestine; Taenia thalami, a superior surface of the thalamus of the mammal brain; Taenia of fourth ventricle, two narrow bands of white matter of the mammal brain
