[Microscopic innervation of the spermatic ducts and testis. I. Vas deferens].
The microscopic innervation of the vas deferens in the rat was studied both in light and electron microscope. The nerve fibres form perivascular, intramuscular and subepithelial plexuses. Inside the connective tissue surrounding the vas deferens both isolated nerve fibres and sensory corpuscles (glomerular and Ruffine-like types) were observed. The varicosities and endings of nerve fibres contain synaptic vesicles of different sizes and electron characteristics. These varicosities were closely related to the smooth muscle cells and some of them lacked of Schwannian sheath. The nervous fibres were not in direct contact with the epithelial cells.
