In anatomy, a stoma (pl.: stomata / ˈ s t oʊ m ə t ə / or stomas) is any opening in the body. For example, a mouth, a nose, and an anus are natural stomata. Any hollow organ can be manipulated into an artificial stoma as necessary. This includes the esophagus, stomach, duodenum, ileum, colon, pleural cavity, ureters, urinary bladder, and ...
The normal thickness of the small intestinal wall is 3–5 mm, [6] and 1–5 mm in the large intestine. [7] Focal, irregular and asymmetrical gastrointestinal wall thickening suggests a malignancy. [ 7 ]
The human stomach has receptors responsive to sodium glutamate [38] and this information is passed to the lateral hypothalamus and limbic system in the brain as a palatability signal through the vagus nerve. [39] The stomach can also sense, independently of tongue and oral taste receptors, glucose, [40] carbohydrates, [41] proteins, [41] and ...

Different classifications of stoma types exist. One that is widely used is based on the types that Julien Joseph Vesque introduced in 1889, was further developed by Metcalfe and Chalk, [23] and later complemented by other authors. It is based on the size, shape and arrangement of the subsidiary cells that surround the two guard cells. [24]
Patient with a colostomy complicated by a large parastomal hernia, which is when tissue protrudes adjacent to the stoma tract. CT scan of same patient, showing intestines within the hernia. Parastomal hernia (PH) is the most common late complication of stomata through the abdominal wall , occurring in 10-25% of patients, [ 10 ] even up to 50% ...
Whilst the muscularis externa is similar throughout the entire gastrointestinal tract, an exception is the stomach which has an additional inner oblique muscular layer to aid with grinding and mixing of food. The muscularis externa of the stomach is composed of the inner oblique layer, middle circular layer, and the outer longitudinal layer.
