Anatomy and Physiology of the Prostate
The adult prostate is a firm, elastic gland having the shape of an inverted pyramid and located at the base of the bladder (Fig. 8.1). It is traversed by the prostatic urethra and the paired ejaculatory ducts, the latter emptying distally on the verumontanum. The verumontanum is a small mound of tissue posteriorly situated in the distal prostatic urethra. It contains a small central cavity communicating with the urethra, the utricle. The average measurements for the prostate are 3.4 cm in length, 4.4 cm in width, and 2.6 cm in thickness. The weight of the normal gland is between 15 and 20 g.
