Question

The two intrinsic nerve plexuses serving the alimentary canal are the ________.
A) solar; sympathetic
B) submucosa; myenteric
C) autonomic; somatic
D) mucosa; submucosa

Accepted Answer

The two intrinsic nerve plexuses serving the alimentary canal are the submucosa plexus and the myenteric plexus. These plexuses are located within the walls of the alimentary canal and are responsible for regulating its motility and secretory activity. The submucosa plexus is located in the submucosal layer of the alimentary canal, while the myenteric plexus is located between the circular and longitudinal muscle layers. These plexuses are part of the enteric nervous system, which functions independently of the central nervous system.
