title: [Microscopic innervation of the spermatic ducts and testis. II. Ductus epididymis].
abstract: The microscopic innervation of the ductus epididymis in the rat has been studied both in light and electron microscope. The nerve fibres form perivascular, intramuscular and subepithelial plexuses. Occasionally sensory formations were observed in the adventitia of the cauda epididymis. The innervation is more abundant in the cauda epididymis than in the other segments (caput and corpus). The varicosities and endings of nerve fibres have synaptic vesicles of different sizes and electron characteristics. Some of the varicosities were close to the muscle cells and without glial sheath. The epithelial cells were not directly innervated.
