The Sympathetic Innervation of the Oviduct in the Rat

Abstract
The adrenergic innervation of the rat oviduct was studied by fluorescence microscopy. The outer half of the circular muscle layer was penetrated by a thin net of adrenergic nerve terminals throughout the isthmus. Adrenergic nerve terminals were scarcely seen in the muscular wall of the ampulla. In the mesotubarium close to the oviduct a dense net of adrenergic nerve terminals were observed. The functional role of the observations is discussed.
