Final answer:
The enteric nervous system is a division of the nervous system responsible for controlling the digestive system, functioning independently of the CNS and as part of the autonomic system.
Step-by-step explanation:
The enteric nervous system (ENS) is a specialized part of the nervous system that is involved in controlling the function of the digestive system. This intricate network of neurons operates largely independently of the central nervous system (CNS), although it is sometimes considered a component of the autonomic nervous system because of its role in regulating digestion through autonomic connections. The ENS is found within the periphery of the body, embedded in the lining of the gastrointestinal system. It consists of myenteric plexuses that enable the direct control of digestive function, such as peristaltic movements and the secretion of digestive enzymes, without requiring input from the CNS. Therefore, the correct answer to the question of which network of neurons controls digestion is B. digestion.
