Summary
The use of the S-100 protein and acetylated alpha-tubulin allowed us to follow the distribution of the glial cells and nerve fibres in the wall of the large intestine of the cat. The results we have obtained show the location of both nerve structures in two ganglionated plexuses: the plexus myentericus and plexus submucosus. The circular layer of the plexus myentericus revealed a high density of positive nerve fibres distributed along the smooth muscle cells. The plexus submucosus is arranged in two sublayers - external and internal. In both sublayers, a dense plexus of nerve fibres were seen, especially around the blood vessels. An aganglionic plexus is formed in the lamina muscularis mucosae. From the internal submucous layer nerve fibres localized in the connective tissue septa run radially into the connective tissue of the lamina propria among the intestinal glands. Positive enteric nerve fibres are located around the occasional lymphatic nodules.
