[Morphological and ultrastructural study of the neural pelvic plexus in the male white mouse]

The hypogastric ganglion which innerves the vas deferens and accessory glands of rat genital tract does not exist in the mouse. The mouse genital tract is innervated by a pelvic plexus made of a network of nervous fibres in which there are nervous ganglia. In these latter, there is a subpopulation of S. I. F. cells characterized by clear synaptic vesicles and a low number of dense core vesicles.
