The central zone constitutes 25 of the glandular prostate.

Zonal anatomy of prostate. The peripheral zone pz contains the majority of prostatic glandular tissue. The peripheral zone surrounds the distal prostatic urethra at the apex of the prostate and extends posterolaterally to the base. The anterior fibromuscular stroma forms the entire anterior surface of the prostate as a thick nonglandular apron shielding from view the anterior surface of the three glandular regions.

Basal one third of the prostate base. It forms a disc of tissue whose ducts radiate laterally from the urethra lateral and distal to the verumontanum. Anatomy of the prostate gland in surgical pathology specimens.

Benign prostatic hyperplasia is a reason for a dramatic increase. Almost all carcinomas arise here. The prostate gland is composed of different types of tissue divided into zones.

The central zone originates probably from the wolffian duct. Prostate zone anatomy prostate cancer and imaging. Its ducts arise close to the ejaculatory duct orifices and follow these ducts proximally branching laterally near the prostate base.

The prostate is comprised of three distinct zones with different embryologic origins. The largest area of the peripheral zone is at the back of the gland closest to the rectal wall. Histologic variation by anatomic region apical one third of the prostate apex.

Middle one third of the prostate mid gland. The large cup shaped peripheral zone pz encompasses the central and transition zones and accounts for approximately 70 of the total prostate volume in a young adult.
