C) They are located in the mucosa.
D) They are located in the brain stem.

Question

Quizplus · Accepted Answer

Intrinsic nerve plexuses, also known as enteric nervous system, coordinate local activity in the digestive tract by regulating smooth muscle contraction, glandular secretion and blood flow. They are located in the submucosa and the muscularis externa layers of the digestive tract. They can generate propagating waves of electrical activity, but not spontaneous depolarization of smooth muscle cells. They are not located in the brain stem.
