[Cholinergic innervation of the prostate in the white rat (Rattus norvegicus)]

We studied the cholinergic innervation of the prostate in male albino rats using a technic for demonstrating acetylcholinesterase (AChE) activity. We observed AChE-positive nerve fibers surrounding the acini and blood vessels. In the prostatic ventral lobe, a large number of AChE-reactive neurons (isolated or forming microganglia) were observed. However, no neurons were observed in the dorsal-lateral prostatic lobe. The foregoing findings suggest a different cholinergic innervation for these prostatic lobes.
