| deep palmar (arterial) arch | The arterial arch located deep to the long flexor tendons in the hand. It is formed by the terminal part of the radial artery in conjunction with the deep palmar branch of the ulnar artery. The arch gives rise to palmar metacarpal and princeps pollicis arteries. Synonym: arcus palmaris profundus, arcus volaris profundus. (05 Mar 2000) |

| diffuse arterial ectasia | Spontaneous enlargement with dilation of the vessels in a circumscribed area. (05 Mar 2000) |
| infusions, intra-arterial | Regional infusion of drugs via an arterial catheter. Often a pump is used to impel the drug through the catheter. Used in therapy of cancer, upper gastrointestinal haemorrhage, infection, and peripheral vascular disease. (12 Dec 1998) |
| intermesenteric arterial anastomosis | The series of arterial arches formed in the mesentery by anastomoses between adjacent jejunal and ileal arteries and from which vasa recta arise. The arterial arcades of the ileum are shorter and more complex than those of the jejunum. See: arterial arches of ileum, arterial arches of jejunum. Synonym: intermesenteric arterial anastomosis, Riolan's arc, Riolan's arcades. (05 Mar 2000) |

| intra-arterial | Into an artery. (16 Dec 1997) |
| intra-arterial pressure | The pressure of the blood within an artery, the arterial pressure. Also called the arterial tension. (12 Dec 1998) |
| tension, arterial | The pressure of the blood within an artery, the arterial pressure. Also called the intra-arterial pressure. (12 Dec 1998) |
| transposition of arterial stems | Congenital malformation in which the aorta arises from the morphologic right ventricle and the pulmonary artery from the morphologic left ventricle resulting in two separate and parallel circulations. The condition is lethal unless some communication exists between the systemic and pulmonic circulation after birth; otherwise, unoxygenated venous blood inappropriately enters the systemic circulation, and oxygenated pulmonary venous blood is inappropriately directed to the pulmonary circulation. The life sustaining communication may be an intra-atrial passage or a patent ductus arteriosus. Synonym: transposition of arterial stems. (05 Mar 2000) |
| anterior cerebral artery | <anatomy, artery> One of the two terminal branches (with middle cerebral artery) of the internal carotid; it passes anterior, loops around the genu of the corpus callosum then posteriorly in the interhemispheric fissure along with its fellow of the opposite side, the two being joined by the anterior communicating artery; for descriptive purposes it is divided into two parts: the precommunical part (A2 segment of clinical terminology), supplying branches to the thalamus and corpus striatum, and the postcommunical part, (A2) or pericallosal artery, supplying branches to the cortex of the medial parts of the frontal and parietal lobes. Synonym: arteria cerebri anterior. (05 Mar 2000) |
| anterior cerebral vein | <anatomy, vein> A small vein that parallels the anterior cerebral artery and drains into the basal vein. Synonym: vena cerebri anterior. (05 Mar 2000) |
| arteries of cerebral haemorrhage | Numerous small branches from the sphenoidal part of the middle cerebral arteries supplying the lateral and anterior parts of the corpus striatum. Synonym: arteriae centrales anterolaterales, arteriae thalamostriatae anterolaterales, anterolateral central arteries, anterolateral striate arteries, anterolateral thalamostriate arteries, arteries of cerebral haemorrhage, lenticulostriate arteries. (05 Mar 2000) |
| ganglionic layer of cerebral cortex | Layer 5 of the cortex cerebri. (05 Mar 2000) |
| malaria, cerebral | A condition that is most commonly seen as a severe complication of malaria, falciparum mainly involving the brain. It has also been reported to occur as a result of infection with other plasmodium species. This disease is often fatal and presents as disturbances in consciousness ranging from somnolence to coma, major motor seizures, and organic psychosis. The onset may be gradual or sudden following a convulsion. (12 Dec 1998) |
| ventricle of cerebral hemisphere | A cavity shaped somewhat like a horseshoe in conformity with the general shape of the hemisphere; each lateral ventricle communicates with the third ventricle through the interventricular foramen of Monro, and expands from there forward into the frontal lobe as the anterior horn as well as caudally over the thalamus as the central part or cella media which, behind the thalamus, curves ventrally and laterally, then forward into the temporal lobe as the inferior horn; from the apex of the curve a variably sized posterior horn extends back into the white matter of the occipital lobe. The large choroid plexus of the lateral ventricle invades the cella media and the inferior horn (but not the anterior and posterior horn) from the medial side. Synonym: ventriculus lateralis, ventricle of cerebral hemisphere. (05 Mar 2000) |
