What is the intramural plexus?

The autonomic nerves enter the internal or-gans together with the vessels and form a fine network of noradrenergic (A) or cholin-ergic (B) fibers (enteric plexus). The fibers terminate on smooth-muscle cells and on glands.

What plexus controls secretions of the GI tract?

The inner plexus is the main control for GI secretion and local blood flow. The myenteric plexus extends throughout the entire length of the gut as a linear chain of interconnected neurons.

What three Plexuses serve the abdominal digestive organs?

Two major nerve centres are involved: the myenteric plexus (Auerbach’s plexus) and the submucous plexus (Meissner’s plexus). The myenteric plexus is situated between the circular muscle layer and the longitudinal muscle layer in the lower esophagus, stomach, and intestines.

Where is Auerbach plexus located in the stomach?

The cells of the Auerbach’s (myenteric) plexus are located between the inner circular and outer longitudinal layers of the muscularis externa. These nerve cells are the portion of the enteric nervous system responsible for generating peristaltic movements.

Where do the nerves of the intramural plexus terminate?

Intramural Plexus The autonomic nerves enter the internal or-gans together with the vessels and form a fine network of noradrenergic (A) or cholin-ergic (B) fibers (enteric plexus). The fibers terminate on smooth-muscle cells and on glands.

Where is the myenteric plexus located in the intestine?

The myenteric plexus (C2) is embedded in a narrow space between the transverse and longitudinal muscles of the intestine. It con-sists of a relatively regular network of coarse and fine fiber bundles. Apart from the intramural ganglia at the intersections, there are numerous neurons that are often arranged in rows along…

Which is plexus is supplied by the digestive tract?

The digestive tract is supplied by two differ-ent plexuses, namely, the submucous plexus (Meissner’s plexus) and the myenteric plexus (Auerbach’s plexus). The submucous plexus(C1, D) forms a three-dimensional network throughout the entire submucosa.

Where is the enteric nervous system located in the body?

The enteric nervous system is embedded in the lining of the gastrointestinal system.
