|---|---|
| BCA-O | bilateral carotid artery occlusion |
| ALCA-PA | Anomalous origin of the left coronary artery from the pulmonary artery |
| STA-MCA | Superficial temporal artery - middle cerebral artery |
| STA-MCA | Superficial temporal artery to middle cerebral artery |
| cervical part of internal carotid artery | <anatomy, artery> The unbranched portion located in the neck. Synonym: pars cervicalis arteriae carotidis internae. (05 Mar 2000) |
|---|---|
| meningeal branch of internal carotid artery | <anatomy, artery> A branch from the cavernous part of the internal carotid artery to the meninges of the anterior cranial fossa. Synonym: ramus meningeus arteriae carotidis internae. (05 Mar 2000) |
| petrous part of internal carotid artery | <anatomy, artery> The part of the internal carotid artery in the carotid canal; its branches are carotidotympanic arteries and the artery of the pterygoid canal. Synonym: pars petrosa arteriae carotidis internae, petrous bone. (05 Mar 2000) |
| common carotid artery | <anatomy, artery> Origin, right from brachiocephalic, left from arch of aorta; runs upward in the neck and divides opposite upper border of thyroid cartilage (C-4 vertebral level) into terminal branches, external and internal carotid. Synonym: arteria carotis communis. (05 Mar 2000) |
| internal carotid artery | <anatomy, artery> Arises from the common carotid opposite upper border of thyroid cartilage (C-4 vertebral level) and terminates in the middle cranial fossa by dividing into the anterior and middle cerebral arteries; for descriptive purposes it is divided into four parts: cervical, petrous, cavernous, and cerebral. Synonym: arteria carotis interna. (05 Mar 2000) |
| external carotid artery | <anatomy, artery> Origin, common carotid at C-4 vertebral level; branches, superior thyroid, lingual, facial, occipital, posterior auricular, ascending pharyngeal, and terminal branches, maxillary and superficial temporal at level of neck of mandible. Synonym: arteria carotis externa. (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) |
| carotid canal | A passage through the petrous part of the temporal bone from its inferior surface upward, medially, and forward to the apex where it opens into the foramen lacerum. It transmits the internal carotid artery and plexuses of veins and autonomic nerves. Synonym: canalis caroticus. (05 Mar 2000) |
