The Prostate Gland [prostate], gl. prostatica [prostata]1 is an unpaired organ weighing 25 g, with a vertical dimension of 3 cm, a horizontal dimension of 4 cm, and a sagittal dimension of 2.5 cm. It is chestnut-shaped (see Fig. 319). The gland comprises the base, basis prostatae, directed toward the Urinary Bladder, and the apex, apex prostatae, directed toward the urogenital Diaphragm, as well as three surfaces: the anterior surface, facies anterior, the posterior surface, facies posterior, and the inferolateral surface, facies inferolateralis. The gland consists of the right and left lobes, prostatae dexter et sinister, the isthmus, isthmus prostatae, and the middle lobe, lobus medius. The middle lobe is located between the Cytology/practical/108.html">Fundus of the urinary bladder and the posterior part of the Urethra, along with both Ductus Deferentes. The excretory ducts of the prostate gland, numbering 20-30, are situated around the seminal colliculus.

1 The term glandula prostatica is inappropriate, since glandular tissue accounts for only two-thirds of the tissue beneath the capsule (Terminologia Anatomica, 1998).
