Smooth Muscle Histology

Histological section from the colon wall, (Stain - Haematoxylin Eosin)

Showing tunica muscularis and myenteric plexus (Auerbach's plexus).


Embryology Historic Terminology The historic name for myenteric plexus is Auerbach's plexus. In 1864 Auerbach first described the myenteric plexus lying between the longitudinal and circular muscle layers.

Gastrointestinal Tract Plexuses (enteric nervous system)
Myenteric plexus Submucosal plexus
Auerbach's plexus Meissner's plexus
Leopold Auerbach (1828–1897) a German anatomist and neuropathologist. Georg Meissner (1829–1905) a German anatomist and physiologist.
  • first formed plexus
  • lies between the outer longitudinal and inner circular smooth muscle layers of muscularis externa
  • provides motor innervation to both layers
  • secretomotor innervation to the mucosa
  • both parasympathetic and sympathetic input
  • forms 2-3 days after the myenteric plexus
  • formed by cells migrating from the myenteric plexus
  • innervates smooth muscle of the muscularis mucosae
  • only parasympathetic fibers
