| vertebral artery | <anatomy, artery> Paired arteries which supply the muscles of the neck, spinal cord and cerebellum. (27 Sep 1997) |
|---|---|
| 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) |

| parieto-occipital artery | <anatomy, artery> The largest cortical branch of the pericallosal artery supplying the medial and superolateral surface of the parietal lobe posterior to the paracentral lobule; rarely does it extend to supply part of the occipital lobe. Synonym: arteria parieto-occipitalis, superior internal parietal artery. (05 Mar 2000) |
