| 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) |
| hepatic arteries | Arteries involved in supplying blood to the liver. See: common hepatic artery, proper hepatic artery, left hepatic artery, right hepatic artery. (05 Mar 2000) |
| screw arteries | Coiled artery's into the uterine mucosa or in the macular region of the retina. (05 Mar 2000) |
| scrotal arteries | See: anterior scrotal branch of external pudendal artery, posterior scrotal branch of internal pudendal artery. (05 Mar 2000) |
| pubic arteries | See: pubic branch of inferior epigastric artery, pubic branch of obturator artery. (05 Mar 2000) |
| segmental arteries of kidney | The branches of the renal artery that supply the anatomical segments of kidney. Usually five in number, they are end arteries and give off interlobar, arcuate and interlobular arteries in sequence. The latter send afferent arterioles to the glomeruli as well as branches to the kidney capsule. The segmental arteries of the kidney are identified as: anterior inferior (arteriae segmenti anterioris inferioris renis ); anterior superior (arteriae segmenti anterioris superioris renis ); inferior (arteriae segmenti inferioris renis ); posterior (arteriae segmenti posterioris renis ); and superior (arteriae segmenti superioris renis ). Synonym: arteriae renis, arteries of kidney. (05 Mar 2000) |
| pulmonary arteries | <anatomy> The pulmonary arteries deliver deoxygenated blood from the right ventricle to the lungs. They are the only arteries in the human body that carry deoxygenated blood. (27 Sep 1997) |
| short gastric arteries | Four or five small arteries given off from the splenic, passing via the gastrosplenic ligament to the fundus of the stomach along the greater curvature, and anastomosing with the other arteries in that region. Synonym: arteriae gastricae breves, vasa brevia. (05 Mar 2000) |
| sigmoid arteries | Origin, inferior mesenteric; distribution, descending colon and sigmoid flexure; anastomoses, left colic, superior rectal. Synonym: arteriae sigmoideae. (05 Mar 2000) |
| small arteries | Unnamed muscular artery's, usually with fewer than six or seven layers of muscle. (05 Mar 2000) |
| somatic arteries | Artery's that arise in the embryo from the dorsal aorta and supply the body wall; they persist almost unchanged as the posterior intercostal, subcostal, and lumbar artery's. (05 Mar 2000) |
| spinal arteries | Branches of the following arteries which supply the meninges, the roots of the spinal nerves, and in some cases, the spinal cord: 1) vertebral, 2) ascending cervical, 3) dorsal branch of posterior intercostal I to XI, 4) dorsal branch of subcostal, 5) dorsal branch of lumbar arteries, 6) lumbar branch of iliolumbar, 7) lateral sacral; all spinal arteries give rise to radicular arteries supplying dorsal and ventral roots of spinal nerves, but some (4-9), are large enough to reach and anastomose with the anterior and posterior spinal arteries. Synonym: rami radiculares. See: medullary spinal arteries, arteria radicularis magna. Synonym: rami spinales. (05 Mar 2000) |
| sternal arteries | <anatomy, artery> Branches of internal thoracic artery which pass medially to supply the transversus thoracis muscle and posterior sternum. Synonym: rami sternales arteriae thoracicae internae, sternal arteries. (05 Mar 2000) |
