Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Vomiting is an example of the central regulation of intestinal motility functions.
A
TRUE.
B
False.
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -GI motility is controlled by contractility of smooth muscles of the GI tract, extrinsic and intrinsic neurons (motor and sensory) and some hormones. In mammals, ghrelin (GHRL) and motilin (MLN) stimulate appetite and GI motility and contribute to the regulation of energy homeostasis.

Detailed explanation-2: -"Motility” is an unfamiliar word to many people; it is used primarily to describe the contraction of the muscles in the gastrointestinal tract. Because the gastrointestinal tract is a circular tube, when these muscles contract, they close off the tube or make the opening inside smaller-they squeeze.

Detailed explanation-3: -While it sounds unpleasant and unusual, it’s possible to vomit up your own fecal matter. Known in medical literature as “feculent vomiting, ‘’ throwing up poop is usually due to some type of blockage in the intestines.

Detailed explanation-4: -As your body prepares to vomit, the major muscles in between the neck and abdomen – the diaphragm, chest wall and the abdominal muscles – all contract at the same time. This puts pressure on the stomach, forcing the contents in the stomach up the throat and through your mouth.
