| coronary arteries | The arteries that supply the heart with oxygenated blood. There are a number of vessels that are important with regard to coronary artery disease, but the right coronary artery, posterior descending, left main coronary artery, left anterior descending and left circumflex are probably the most frequently surgically grafted coronary vessels.

|---|---|
| cortical arteries | Branches of the anterior, middle, and posterior cerebral artery's that supply the cerebral cortex. (05 Mar 2000) |
| myometrial arcuate arteries | Branches of the uterine and ovarian artery's. (05 Mar 2000) |
| myometrial radial arteries | Continuations of the myometrial arcuate artery's. (05 Mar 2000) |
| pontine arteries | Several small branches of the basilar artery distributed to the pons. Synonym: arteriae pontis, rami ad pontem. (05 Mar 2000) |
| posterior intercostal arteries | Terminal branches of the superior intercostal artery (from costocervical trunk) supplying upper two intercostal spaces (1-2). Posterior intercostal arteries 3-11, one of nine pairs of arteries arising from the thoracic aorta and distributed to the nine lower intercostal spaces, vertebral column, spinal cord, and muscles and integument of the back; they anastomose with branches of the musculophrenic, internal thoracic, superior epigastric, subcostal and lumbar. Synonym: arteriae intercostales posteriores. (05 Mar 2000) |
| posterior labial arteries | The posterior labial branches, branches of the perineal artery to the labium majus. Synonym: rami labiales posteriores arteriae pudendae internae. (05 Mar 2000) |
| posterior lateral nasal arteries | Branches of the sphenopalatine artery that supply the posterior parts of the conchae and lateral nasal wall. Synonym: arteriae nasales posteriores laterales. (05 Mar 2000) |
| posterior mediastinal arteries | Numerous small arteries supplying the pleura and lymph nodes of the posterior mediastinum. Synonym: rami mediastinales aortae thoracicae, posterior mediastinal arteries. (05 Mar 2000) |
| posterior peroneal arteries | Lateral malleolar branches of peroneal artery. Synonym: rami malleolares laterales, arteriae malleolares posteriores laterales, posterior peroneal arteries. (05 Mar 2000) |
| posterolateral central arteries | The circumflex mesencephalic branches, several small branches of the postcommunical part of the posterior cerebral artery distributed to the lateral posterior part of the midbrain. Synonym: arteriae centrales posterolaterales. (05 Mar 2000) |
| posteromedial central arteries | The interpeduncular perforating branches, several small branches from the precommunical part of the posterior cerebral artery supplying the posterior medial part of the midbrain. Synonym: arteriae centrales posteromediales. (05 Mar 2000) |
| helicine arteries of the penis | The coiled terminal branches of the deep and dorsal arteries of the penis. Parasympathetic stimulation causes them to uncoil, allowing blood at arterial pressure to fill the cavernous tissue causing erection. Synonym: arteriae helicinae penis. (05 Mar 2000) |
