[Innervation of the ventral prostate of the rat: ultrastructural study].

: The innervation of the rat ventral prostate was studied at the ultrastructural level. The nerve fascicles, amyelinics, are found in the interstitial tissue of the gland. We have observed varicosities with synaptic vesicles in close contact with the smooth muscle and epithelial cells. Inside the nerve endings, 5 types of vesicles could be distinguished. The role of the different nerve endings is discussed.
