[Neuronal organization of the myenteric plexus (Auerbach) in the swine small intestine. III. Type III neurons].

Dogiel's type III-cells are a reality. According to our investigation they are characterized by the following mean features: 1. Type III-cells are radiate multidendritic (longdendritic, tapering) uniaxonal neurons. 2. Type III-neurons are frequent and represent a independent population of neurons. 3. Type III-cells are on principle concentrated in aggregates and are localized in the central and aboral parts of the ganglia. 4. The greater part of the neurits of type III-cells run aborally, i.e. there are typespecific descending routes within the plexus myentericus (Auerbach). 5. Type III-cells are preferred vascularized neurons.
