Overview: Muscularis externa

Muscularis externa of the stomach has inner oblique (an inconsistent layer), middle circular, and outer longitudinal layers; only the latter two layers are seen here.  Auerbach’s plexus, located between circular and longitudinal muscle layers, provides fibers from the autonomic nervous system to muscularis externa.  A serosa is the outermost tunic.  100x, 800x
