Detailed explanation-1: -Two major nerve centres are involved: the myenteric plexus (Auerbach’s plexus) and the submucous plexus (Meissner’s plexus).
Detailed explanation-2: -The cervical plexus provides nerve connections to the head, neck, and shoulder. The brachial plexus provides connections to the chest, shoulders, upper arms, forearms, and hands. The lumbar plexus provides connections to the back, abdomen, groin, thighs, knees, and calves.
Detailed explanation-3: -The ENS consists of two plexuses, the submucosal and the myenteric. The myenteric plexus increases the tone of the gut and the velocity and intensity of contractions. The submucosal plexus is involved with local conditions and controls local secretion, absorption, and muscle movements.
