Question

which division of the ans consists of an extensive network of neurons and nerve networks located in the walls of the digestive tract?

Explanation:

The enteric division of the autonomic nervous system (ANS) is a complex network of neurons and nerve plexuses located within the walls of the digestive tract. It can operate somewhat independently to regulate digestive functions like peristalsis, secretion, and blood flow in the gut. The somatic nervous system controls voluntary movements. The sympathetic and parasympathetic divisions of the ANS are more about the "fight - or - flight" and "rest - and - digest" responses respectively, but they are not the specific division with the extensive network in the digestive tract walls like the enteric division.

Answer:
