[The external submucous plexus (Schabadasch) in the small intestine of the swine. I. Form, structure and connections of ganglia and nerve cells].

1. There are described principles of organization of the plexus submucous externus (Schabadasch) in the small intestine of the pig. They can be summarized under the term of polarization of nerve cells. 2. The principle of polarization is realized for instance by the formation of type I and type II cell aggregates and by the specific course of the processes of both cell types. 3. These criteria of organization which are much clearer in the pig than in other animals, recommend the plexus Schabadasch of the pig as a suitable model for further investigations.
