Final answer:
The regulation of secretion and motility within the digestive system that is not part of the autonomic system is called the enteric nervous system (ENS), which is responsible for controlling the smooth muscle and glandular tissue in the digestive system.
Step-by-step explanation:
The regulation of secretion and motility within the digestive system that is not part of the autonomic system is called the enteric nervous system (ENS). The ENS is responsible for controlling the smooth muscle and glandular tissue in the digestive system. It is sometimes considered a part of the autonomic system because the ENS is involved in the autonomic output that regulates digestion.
