PATHOLOGY

Detailed explanation-2: -A reflex is an involuntary (say: in-VAHL-un-ter-ee), or automatic, action that your body does in response to something-without you even having to think about it. You don’t decide to kick your leg, it just kicks. There are many types of reflexes and every healthy person has them.

Detailed explanation-3: -Medulla controls the involuntary actions performed by the internal organs of the body and digestion is one of such involuntary actions performed by the stomach.
