| internal mammary-coronary artery anastomosis | Direct myocardial revascularization in which the internal mammary artery is anastomosed to the right coronary artery, circumflex artery, or anterior descending coronary artery. The internal mammary artery is the most frequent choice, especially for a single graft, for coronary artery bypass surgery. (12 Dec 1998) |
|---|---|
| internal maxillary artery | <anatomy, artery> A branch of the external carotid artery which distributes to the deep structures of the face (internal maxillary) and to the side of the face and nose (external maxillary). (12 Dec 1998) |
| internal pudendal artery | <anatomy, artery> Origin, internal iliac; branches, inferior rectal, perineal, posterior scrotal (or labial), urethral, artery of bulb of penis (or of vestibule), deep artery of penis (or clitoris), dorsal artery of penis (or clitoris). Synonym: arteria pudenda interna. (05 Mar 2000) |
| internal spermatic artery | <anatomy, artery> Origin, aorta; branches, ureteral, cremasteric, epididymal; distribution, testicle and parts designated by names of branches; anastomoses, branches of renal, inferior epigastric, deferential. Synonym: arteria testicularis, arteria spermatica interna, internal spermatic artery. (05 Mar 2000) |
| internal thoracic artery | <anatomy, artery> Origin, subclavian; branches, pericardiacophrenic, anterior intercostal, sternal, mediastinal, thymic, bronchial, muscular, and perforating branches, and bifurcates into the musculophrenic and superior epigastric. Synonym: arteria thoracica interna, arteria mammaria interna, internal mammary artery. (05 Mar 2000) |
| thymic branches of internal thoracic artery | <anatomy, artery> See: mediastinal branches of internal thoracic artery. (05 Mar 2000) |
| lateral costal branch of internal thoracic artery | <anatomy, artery> A variable branch of internal thoracic artery that runs lateral and parallel to the internal thoracic artery on the deep surface of the rib cage; anastomosis: posterior intercostal arteries. Synonym: ramus costalis lateralis arteriae thoracicae internae. (05 Mar 2000) |
| anastomotic branch of middle meningeal artery to lacrimal artery | <anatomy, artery> A branch of the middle meningeal artery arising in the cranial cavity which runs anteriorly through the superior orbital fissure to anastomose with the lacrimal artery. See: orbital branch of middle meningeal artery. Synonym: ramus anastomoticus arteriae meningeae mediae cum lacrimali. (05 Mar 2000) |
| carotid | Pertaining to the carotid artery. (12 Dec 1998) |
| carotid arteries | <anatomy> Paired large calibre vessels that pass on either side of the neck supplying oxygenated blood to the brain. Occlusive disease (atherosclerosis) of the vessels can lead to stroke. (27 Sep 1997) |
| carotid body | A small cluster of chemoreceptive and supporting cells located near the bifurcation of the internal carotid artery. The carotid body, which is richly supplied with fenestrated capillaries, senses the pH, carbon dioxide, and oxygen concentrations in the blood and plays a crucial role in their homeostatic control. (12 Dec 1998) |
| carotid body cell | <pathology> Cells derived from the neural crest, involved in sensing pH and oxygen tension of the blood. (18 Nov 1997) |
| carotid body tumour | An invariably benign, encapsulated, firm round mass at the bifurcation of the common carotid artery, with nests of large polyhedral cells in alveolar or organoid arrangement. It is usually asymptomatic but large masses may encroach upon the parapharyngeal space and produce dysphagia, pain, and cranial nerve palsies. (12 Dec 1998) |
| carotid bruit | <cardiology, clinical sign> A systolic murmur heard at the root of the neck (over a carotid artery) that is produced by turbulence from a blockage of blood flow in the vessel, can indicate carotid artery occlusive disease. See: stroke. (27 Sep 1997) |
| carotid bulb | <anatomy> A slight dilation in the carotid artery at its bifurcation into the external and internal carotid arteries, it contains baroreceptors (pressure sensors) that when stimulated, will cause a reflex slowing of the heart, vasodilation and a fall in blood pressure. (27 Sep 1997) |
