Smooth muscle

Smooth muscle, the most widespread of the muscle types, is often organized into perpendicularly oriented sheets in the walls of tubular organs.  In such locations, the muscle mixes and propels luminal contents.  Here, a cross section of small intestine shows inner circular and outer longitudinal smooth muscle sheets forming much of the intestinal wall.  400x
