MCQ Physiology Answer 12

The Correct Answer is C

Auerbach's plexus and the myenteric plexus are one and the same.

The submucosal plexus contains fewer neurons than the myenteric plexus. The submucosal plexus is most prominent in the small and large intestines. Both plexuses are continuous around the GI tract and along its length. The two plexuses are distinct; however, interconnections bind the network into a functionally unified nervous system.

Efferent vagal innervation may excite or inhibit GI effectors. Efferent sympathetic stimulation suppresses motility and secretion, decreases blood flow to intestinge and contracts sphincter muscles.
