Glandular region

Posterior and largest portion of the prostate gland.

Includes four zones:

1) peripheral zone,

2) central zone,

3) transition zone,

4) periurethral zone.



Central zone

A zone of the glandular prostate



Accounts for 20% of the gland



Located: at the superior edge bordering the bladder and seminal vesicles



Peripheral zone

The largest (70%) of four zones or areas that make up the posterior glandular portion of
the prostate gland.

It occupies the area lateral and posterior to the distal prostatic urethra.



Periurethral glandular zone

Consists of tissue that lines the proximal prostatic urethra

, Transition zone

Accounts for 5% of the glandular prostate

It has two lobes situated on the lateral aspects of the proximal prostatic urethra
superior to the verumontanum.

This zone borders the central zone posteriorly and laterally and fibromuscular tissue
anteriorly



Denonvillier's fascia

Two-layered fascia separating the prostate gland from the rectum.



Duchus (vas) deferens

One of two muscular tubes each joining with its corresponding seminal vesicle to form
the ejaculatory duct



Ejaculatory duct

Two ducts that course through the prostate gland and empty into the prostatic urethra



prostatic urethra

Portion of the male urethra surrounded by the prostate gland and its adjacent to the
urinary bladder



Prostate gland

Gland surrounding the neck of the urinary bladder and male urethra. Supplies a
secretion to semen



Semen

Fluid that contains sperm and secretions of glands associated with the male urogenital
tract.
