[The neuronal organization of the plexus myentericus (Auerbach) in the small intestine of the pig. II. Typ II-neurone (author's transl)].

The population of type II-neurons in the Auerbach's plexus of the pig's small intestine consisting of bipolar, pseudo-unipolar, and multipolar elements could be characterized a.o. as follows: 1. The type II-cells are on principle concentrated in aggregates in the periphery and outside the ganglia. 2. The processes of type II-cells all leaving the ganglia or aggregates of origin, are of the same axonal structure. Considering further characteristics type II-cells are defined therefore as adendritic, multiaxonal neurons. 3. Contrary to the axons of the other multidendritic, uniaxonal types of neurons (type I, III, IV, V) those of type II-cells forming circular routes (besides the vertical ones) in the secondary branches of Auerbach's plexus can be followed up to the intramuscular plexus. That's why the type II-cells finally can be considered as adendritic, multiaxonal, and efferent neurons.
