Description
Abstract
The ultrastructure organization of the
stomach enteric plexus was examined in the lizard
Podarcis hispanica. The ganglions of the myenteric
plexus present a low number of nerve cell bodies with a
peculiar nucleus, which occasionally establish direct
contacts with cells of the circular muscle layer. Glial
cells are smaller than the neurones, and their nucleus is
very electron-dense. They surround the axons that
constitute the fibres of the myenteric plexus. Four main
types of axon profile are described in a morphological
consideration of the vesicle population. In the interstice
of the circular muscle layer we describe two types of
interstitial cells that, due to their ultrastructural
characteristics, may be equivalent to the interstitial cells
of Cajal which have been described in mammalians.
These cells shows parallel distribution to the stomach
nerve plexuses, establishing close contacts with them
through their long cytoplasmic prolongations. By means
of small gap-like unions, they contact both each other
and the smooth muscle cells near them. We describe a
submucous plexus, where neuronal bodies are scattered
among bundles of nervous fibres, some of which are
myelinated. A mucous plexus with isolated neurones is
located in the lamina propria. Axonal varicosities
containing vesicles contact with the cells of the mucous.
Interconnected interstitial cells may also be found in this
plexus.
