Question

the smooth muscle of the digestive viscera is served largely by the

a) pelvic nerves

b) lumbar splanchnic nerves

c) vagus (x) nerves

d) cephalic plexus

Explanation:

The vagus (X) nerves play a crucial role in the parasympathetic innervation of the digestive system. They are responsible for regulating the smooth muscle contractions in the digestive viscera, which are essential for processes like peristalsis. The pelvic nerves mainly affect the lower - pelvic organs (not the main digestive viscera). The lumbar splanchnic nerves are more related to sympathetic functions in the abdominal region. The cephalic plexus is not the primary nerve supply for the digestive viscera's smooth muscle.

Answer:

C. vagus (X) nerves
