Prostate

The prostate is another gland, whose secretion is added to the seminal fluid.

Its base is in contact with the neck of the bladder and the first portion of the urethra pierces it longitudinally through its center, from base to apex.

Being slightly flattened in the anteroposterior direction, it has an anterior and a posterior face, and on each side, inferolateral faces.

Structurally, the prostate is surrounded by a capsule made up of connective tissue and smooth muscle fibers, from which fine trabeculae depart that go deep into the parenchyma.

Participating in its framework, we find striated muscle fibers that seem to derive from the urethral sphincter muscle.

The rest of the parenchyma is occupied by glandular cells distributed in branched tubes, whose secretion is drained by the prostatic ducts, which, in number around twenty, open on the posterior surface of the interior of the urethra, on each side of the seminal colliculus.
