| artery, carotid | A key artery located in the front of the neck that carries blood from the heart to the brain. (12 Dec 1998) |
|---|---|
| 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 artery | <anatomy, artery> A key artery located in the front of the neck that carries blood from the heart to the brain. Cholesterol plaques on the inner wall of the carotid artery can lead to stroke. (12 Dec 1998) |
| carotid artery bruit | <radiology> Differential diagnosis: Atherosclerotic plaque or stenosis in common carotid artery or major vessels., Normal vessel. Asymptomatic bruits are a risk factor for stroke, and 75% of strokes occur in the carotid circulation. The majority of patients with bruits will have stenosis of 50% or more. The vast majority (90%) of strokes occur without prior symptoms. REF: MacNeil BJ, Abrams HL. Brigham and Women's Hospital Handbook of Diagnostic Imaging. Chapter 27. (12 Dec 1998) |
| carotid artery, common | The two principal arteries supplying the structures of the head and neck. They ascend in the neck, one on each side, and at the level of the upper border of the thyroid cartilage, each divides into two branches, the external (carotid artery, external) and internal (carotid artery, internal) carotid arteries. (12 Dec 1998) |
| carotid artery, external | Branch of the common carotid artery which supplies the exterior of the head, the face, and the greater part of the neck. (12 Dec 1998) |
| carotid artery occlusive syndrome | <syndrome> Aortic arch syndrome, also referred to by many as vertebral-basilar artery disease, carotid artery occlusive syndrome and subclavian steal syndrome. Characterised by a constellation of signs and symptoms which occur secondary to abnormalities in the major arteries which extend off of the aortic arch. These abnormalities are structural and most often secondary to the effects of atherosclerosis, blood clots, trauma or a congenital abnormality. Symptoms of this condition include various neurologic symptoms, reduction in pulse and changes in blood pressure. (27 Sep 1997) |
| carotid artery thrombosis | Formation of a clot in a carotid artery often resulting from atherosclerosis. Patients are at high risk for developing stroke. (12 Dec 1998) |
| 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) |
