Structure of the myenteric plexus in the sphincters of cat gastro-intestinal tract. V. Ultrastructure of the nerve cell bodies and dendrites.
A description is given of the nerve cell bodies and dendrites in the myenteric ganglia in the lower esophageal, pyloric and ileo-caecal sphincters of cats. The perikarya within one ganglion are differentiated depending on the position and predominance of one type of intracellular organelles or another. The question is raised whether these differences are a manifestation of the functional state, age characteristics or functional differentiation. The neurones in the myenteric plexus of the sphincters are characterized by the variety of dendrite branches, differing in shape and size.
