The peripheral zone occupies which regions of the prostate?

Explanation:
The gland is divided into zones with distinct locations. The peripheral zone forms the outer layer on the back and sides of the prostate and extends toward the apex, occupying the posterior and lateral aspects (and part of the apical region). This is the region that makes up most of the gland’s tissue and is the usual site where prostate cancers arise. In contrast, the central zone surrounds the ejaculatory ducts, the transitional (periurethral) zone encloses the urethra and enlarges with BPH, and the anterior fibromuscular stroma sits at the front. So, the peripheral zone corresponds to the posterior, lateral, and apical regions.
