Alimentary gut ganglia (Meissner and Auerbach)
11.2.1 POJA-L3217+3220+3304
Title: Alimentary gut ganglia (Meissner and Auerbach)
Description:
(A): Stain Azan, human. Duodenum with Meissner plexus (1), located in the lamina propria of the mucosa layer. (1) Ganglion cells. (2) Crypts. (3) Brunner glands.
(B): Stain Azan, colon, human. Plexus of Auerbach located between the two muscular layers. The large ganglion cells are surrounded by small amphicytes.
(C): Electron microscopy, rabbit. Synapse ( blue arrow). Dense core granules (blue *) in the afferent axons.
Background: Meissner and Auerbach ganglion cells belong to the enteric nervous system. They derive their supply from the nervus
vagus and thoracic splanchnic nerves through the coeliac ganglia and superior mesenteric plexuses.
Parasympathetic innervation augments peristalsis and inhibits sphincter activity.
Sympathetic innervation inhibits peristalsis but stimulates sphincters and muscularis mucosae.
Keywords/Mesh: nervous tissue, digestive tract, duodenum, colon, plexus of Meissner, plexus of Auerbach, parasympathetic nerve, ganglion cell, axon, histology, electron microscopy, POJA collection
