| prostatic plexus | An autonomic plexus of nerves intimately associated with the capsule of the prostate, derived from the inferior hypogastric plexus, and giving rise to the cavernous nerves to the erectile tissue of the penis; surgical injury of this plexus ofter results in impotency. Synonym: plexus prostaticus. (05 Mar 2000) |
|---|---|
| prostatic sheath | Loose fibrous, partly vascular enclosure of the prostate and its dense (true) fibrous capsule; it is continuous inferiorly with the superior fascia of the urogenital diaphragm and posteriorly becomes part of the rectovesical septum; it contains the prostatic venous plexus. (05 Mar 2000) |
| prostatic sinus | The groove on either side of the urethral crest in the prostatic part of the urethra into which the prostatic ducts open. Synonym: sinus prostaticus. (05 Mar 2000) |
| prostatic urethra | The prostatic part of the male urethra, about 2.5 cm in length, that traverses the prostate; it includes the seminal colliculus, and the ejaculatory and prostatic ducts open into it. Synonym: pars prostatica urethrae. (05 Mar 2000) |
| prostatic utricle | A minute pouch in the prostate opening on the summit of the seminal colliculus, the analogue of the uterus and vagina in the female, being the remains of the fused caudal ends of the paramesonephric ducts. Synonym: utriculus prostaticus, masculine uterus, Morgagni's sinus, sinus pocularis, uterus masculinus, vagina masculina, vesica prostatica, Weber's organ. (05 Mar 2000) |
| prostatic venous plexus | A venous plexus, arising chiefly from the dorsal vein of the penis, situated below the base of the bladder at the sides of the prostate. See: prostaticovesical plexus. Synonym: plexus venosus prostaticus, plexus pudendalis, Santorini's labyrinth. (05 Mar 2000) |
| Young prostatic tractor | A short, straight tubular instrument with blades at its tip, which can be rotated open and closed; it is passed into the prostatic urethra, through a prostatotomy incision made during the later stages of open perineal prostatectomy, with its tip into the bladder; direct traction on the instrument brings the prostate gland down into the operative field where enucleation can be more easily performed. (05 Mar 2000) |
| anterior auricular branches of superficial temporal artery | <anatomy, artery> Distribution, auricle, earlobe and external acoustic meatus. Synonym: rami auriculares anteriores arteriae temporalis superficialis. (05 Mar 2000) |
| anterior cutaneous branches of intercostal nerves | Medial mammary branches of anterior cutaneous branches of ventral primary rami of thoracic spinal nerves. See: medial mammary branches. (05 Mar 2000) |
| anterior intercostal branches of internal thoracic artery | One of the arteries supplying the anterior portions of the intercostal spaces of the thoracic wall. Anterior intercostal arteries 1-6 arise as branches of the internal thoracic artery; 7-11 arise as branches of the musculophrenic artery. Synonym: rami intercostales anteriores, rami intercostalis anteriores arteria thoracica interna. (05 Mar 2000) |
| anterior superior alveolar branches of infraorbital nerve | <anatomy, nerve> The branches of the superior alveolar nerve that supply the incisors, canines, premolars, and first molar by their contributions to the superior dental plexus. Synonym: rami alveolares superiores anteriores nervi infraorbitalis. (05 Mar 2000) |
| anteromedial central branches | Branches of the anterior communicating artery which supply part of the hypothalamus. Synonym: rami centrales anteromediales. (05 Mar 2000) |
| articular branches | Branches distributed to joints. Almost any vessel related to a joint will supply articular rami. Most joints receive articular branches from the intramuscular branches of the motor nerves innervating the muscles crossing the joint (see Hilton's law). at this printing, Nomina Anatomica, however, specifically recognises only the articular branches of the descending genicular artery, ramus articulares arteriae descendentis genicularis; supplying the knee joint. Synonym: rami articulares, joint branches. (05 Mar 2000) |
| atrial branches | The atrial branches, the branches of the right coronary artery and the circumflex branch of the left coronary artery distributed to the right and left atrium, respectively. Synonym: rami atriales. (05 Mar 2000) |
| branches of segmental bronchi | Branches of segmental bronchi to the bronchopulmonary segments of the lungs. Synonym: rami bronchiales segmentorum. (05 Mar 2000) |
