title: Direct contacts between Auerbach's ganglia and smooth muscle cells in the small intestine of the rat.
abstract: The present electron microscopic study demonstrated direct contacts between Auerbach's ganglia and longitudinal smooth muscle cells in the rat small intestine. The muscle cells were often observed to extend small, foot-like processes to the Auerbach's ganglia. These processes were in contact with glial cells in the ganglia without an intervening basal lamina, or were in contact with intraganglionic axon varicosities containing many synaptic vesicles. The processes in contact with glial cells may anchor the muscle cells to the ganglia during muscle contraction and those in contact with axon varicosities may function as synaptic sites between ganglion and longitudinal muscle cells.
