| vascular meninx | <anatomy> Rarely used term for pia mater. Synonym: meninx vasculosa. (05 Mar 2000) |

| meninx | Any membrane; specifically, one of the membranous coverings of the brain and spinal cord. See: arachnoidea, dura mater, pia mater. Origin: Mod. L. Fr. G. Meninx, membrane Meninx fibrosa, rarely used term for dura mater. (05 Mar 2000) |
|---|---|
| meninx primitiva | The embryonic loose mesenchymatous tissue surrounding the brain and spinal cord; from it the three definite meninges (arachnoidea, dura mater, and pia mater) are derived. Synonym: meninx primitiva. Meninx serosa, obsolete term for arachnoidea; the arachnoid is actually not a serous membrane. (05 Mar 2000) |
| meninx tenuis | The two delicate layers of the meninges, the arachnoid mater and pia mater (vs. The tough pachymeninx or dura mater), considered together; by this concept, the arachnoid and pia are two parts of a single layer, much like the parietal and visceral layers of a serous membrane or bursa; although separated by the subarachnoid space they are connected via the arachnoid trabeculae and become continuous where the nerves and filum terminale exit the subarachnoid space (the cerebrospinal fluid-filled space bounded by the leptomeninges). See: arachnoid, pia mater. Synonym: meninx tenuis, pia-arachnoid, piarachnoid. Origin: Lepto-+ G. Meninx, pl. Meninges, membrane (05 Mar 2000) |
| meninx vasculosa | <anatomy> Rarely used term for pia mater. Synonym: meninx vasculosa. (05 Mar 2000) |
| primitive meninx | The embryonic loose mesenchymatous tissue surrounding the brain and spinal cord; from it the three definite meninges (arachnoidea, dura mater, and pia mater) are derived. Synonym: meninx primitiva. Meninx serosa, obsolete term for arachnoidea; the arachnoid is actually not a serous membrane. (05 Mar 2000) |
| acute vascular occlusion | <cardiology, surgery> A serious condition that results from the sudden blockage of an artery, usually with a blood clot. (27 Sep 1997) |
| acute vascular purpura | <dermatology> This relatively rare disorder is characterised by skin purpura, joint pains, abdominal pain and renal disease (glomerulonephritis). Although Henoch-Schonlein purpura or anaphylactoid purpura, is thought to be a immune complex mediated disease, its exact cause is unknown. Its typical benign coarse can, however, include renal failure. (27 Sep 1997) |
| articular vascular circle | An anastomosis of vessels encircling a joint. See: articular vascular network. Synonym: circulus articularis vasculosus. (05 Mar 2000) |
| articular vascular network | A vascular rete in the neighborhood of a joint, where such arrangements are common, enabling a collateral circulation by which blood will be supplied distal to the joint regardless of compromises resulting from joint position. Synonym: circulus articularis vasculosus, rete vasculosum articulare, articular network. (05 Mar 2000) |
| articular vascular network of elbow | Vascular networks in the region of the elbow, composed of anastomoses between branches of the radial and middle collateral, superior and inferior ulnar collateral, radial recurrent, interosseous recurrent, and recurrent ulnar arteries. Synonym: rete articulare cubiti. (05 Mar 2000) |
| articular vascular network of knee | An arterial network over the front and sides of the knee, formed by branches of the descending genicular artery, of the five genicular arteries from the popliteal, of the anterior tibial recurrent, and of the fibular circumflex branch of the posterior tibial. Synonym: rete articulare genus. (05 Mar 2000) |
| atherosclerotic vascular disease | <cardiology> The progressive narrowing and hardening of the arteries over time. This is known to occur to some degree with aging, but other risk factors that accelerate this process have been identified. These factors include: high cholesterol, high blood pressure, smoking, diabetes and family history for atherosclerotic disease. (27 Sep 1997) |
| blood-vascular system | The heart and the blood vessels by which blood is pumped and circulated through the body. (12 Dec 1998) |
| vascular | <physiology> Pertaining to blood vessels or indicative of a copious blood supply. (18 Nov 1997) |
| vascular anticoagulant | <protein> Group of calcium-binding proteins that interact with acidic membrane phospholipids in membranes. They contain 4 or 8 repeats of a 61 amino acid domain that folds into 5 a helices. Also known by several other names (e.g. Lipocortins, endonexins), reflecting the history of their discovery in different contexts. See: lipocortin, endonexin I & II, calpactin, p70 and calelectrin.
