To regulate motility through the digestive tract to regulate salivation
The enteric nervous system, the rather autonomous component of the nervous system, is formed from several neural circuits that regulate motor and local blood flow as well as immunological and endocrine activity as well as motor and local blood flow.
The myenteric (Auerbach) and submucosal (Meissner) plexuses are the main parts of the ENS. The myenteric plexus controls the relaxation and contraction of the intestinal wall and is situated between the longitudinal and circular smooth muscle layers. The ENS, commonly referred to as "the second brain" or "the gut brain," may autonomously regulate intestinal absorption and digestion.
