| prostate-specific antigen | <tumour marker> A simple blood test used to detect prostate cancer in men. The test measures a specific antigen normally secreted by the prostate. If cancer is developing, the prostate secretes greater amounts of prostate-specific antigen. This test is recommended for men with an enlarged prostate and an increased risk of prostate cancer. It is an enzyme that is produced by epithelial cells of both benign and malignant prostate tissue. It is an important marker for the diagnosis of prostate cancer. It is a single chain 31 kilodalton glycoprotein with 240 amino acid residues and 4 carbohydrate side chains that is a kallikrein protease. It is found in normal seminal fluid and produced by the prostatic epithelial cells. Elevated levels in blood serum are associated with prostatic enlargement and prostatic adenocarcinoma, and this allows early detection of cancer in many cases. In about 70% of cases, the rise is due to a cancerous condition. No large scale clinical studies have been completed to assess the impact of testing on survival from prostate cancer, and the medical and economic value of testing remain uncertain.

| nodular hyperplasia of prostate | Glandular and stromal hyperplasia occurring very commonly in the middle and lateral lobes of older men, forming nodules that may increasingly obstruct the urethra. Synonym: benign prostatic hypertrophy. (05 Mar 2000) |
| inferolateral surface of prostate | The surface of the prostate facing the body of the pubis and the pelvic diaphragm. Synonym: facies inferolateralis prostatae. (05 Mar 2000) |
| elevator muscle of prostate | <anatomy> In the male, the most medial fibres of the levator ani (pubococcygeus) muscle that extend from the pubis into the fascia of the prostate. Synonym: musculus levator prostatae, elevator muscle of prostate. (05 Mar 2000) |
| fascia of prostate | The condensation of pelvic visceral fascia that encloses the prostate gland. Synonym: fascia prostatae. (05 Mar 2000) |
| female prostate | Term sometimes applied to the periurethral glands in the upper part of the urethra in the female. (05 Mar 2000) |
| lobe of prostate | One of the lateral lobes (right or left) or the middle lobe or isthmus of the prostate; in the adult the lobes are ill-defined. Synonym: lobus prostatae. (05 Mar 2000) |
| Vieussens' isthmus | A muscular ring surrounding the fossa ovalis in the wall of the right atrium of the heart. Synonym: annulus ovalis, margin of fossa ovalis, Vieussens' annulus, Vieussens' isthmus, Vieussens' limbus, Vieussens' ring. (05 Mar 2000) |
| rhombencephalic isthmus | A constriction in the embryonic neural tube delineating the mesencephalon from the rhombencephalon, the anterior portion of the rhombencephalon connecting with the mesencephalon. Synonym: isthmus rhombencephali, isthmus of His. (05 Mar 2000) |
| Guyon's isthmus | An elongated constriction at the junction of the body and cervix of the uterus. Synonym: isthmus uteri, Guyon's isthmus, orificium internum uteri, os uteri internum, ostium uteri internum. (05 Mar 2000) |
| pharyngeal isthmus | Communicating space between nasopharynx and oropharynx, sealed off by elevation of the soft palate and contraction of portions of the superior pharyngeal constrictor (palatopharyngal sphincter) during swallowing. (05 Mar 2000) |
| sphincter of the pharyngeal isthmus | A constant band of the superior pharyngeal constrictor muscle which sweeps posteriorly from the anterolateral part of the superior surface of the palatine aponeurosis. It creates a visible ridge when the superior constrictor is contracted, meeting the elevated soft palate to seal off the pharyngeal isthmus during swallowing. Synonym: pharyngeal ridge, sphincter of the pharyngeal isthmus, velopharyngeal sphincter. (05 Mar 2000) |
| isthmus | Origin: L. Isthmus, Gr. 'isqmos a neck, a neck of land between two seas, an isthmus, especially the Isthmus of Corinth; prob. From the root of 'ienai to go; cf. Icel. Eith isthmus.
