[The morphological characteristics of the parasympathetic innervation of the pyloric sphincter in the cat].
The method of axonal transport of horse-radish peroxidase was used to detect the localization of neurons in the dorsal motor nucleus of the vagus nerve sending the axons to the pyloric sphincter. The investigation was carried out in cats. Under study were also morphological features of the nodular ganglion responsible for afferent innervation of the sphincter. The maximum amount of the corresponding cells are found in the dorsomedial part of the dorsal motor nucleus in the area from +1.0 to +2.0 mm (with respect to obex). The afferent neurons to which information comes from interoceptors of the sphincter zone along the vagus nerve fibers, are distributed in the left and right nodular ganglia almost evenly. The major part of these cells have the area of 300-800 mkm2.
