Summary
Auerbach's plexus was studied histologically in the intestines of 27 healthy cats and kittens. Besides the differentiated neurons, neuroblasts were revealed in the ganglia of the intermuscular plexuses. In animals the number of these neuroblasts gradually increases during the first several months of life.
Peripheral glia in the plexus ganglia have 2 variations of the neuroglial syncytium. The first is in the form of a protoplasmatic mass with scattered nuclei, while the second is in the form of nuclear-protoplasmic areas with a tendency to separation of the cellular elements. The latter are morphologically similar to neuroblasts. The intensity of the process of separation of neuroblasts from the neuroglial syncytium is connected, in the author's opinion, with the functional activity of the digestive tract.
