Innervation of the rat preputial gland.

Acetylcholinesterase, butyrylcholinesterase and monoamine oxidase activities were observed in the neuronal and non-neuronal components of the preputial gland. Histological, histochemical and experimental studies clearly indicate that the preputial gland of the rat is innervated by cholinergic as well as adrenergic nerves.
