| 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. (18 Nov 1997) |
| vascular bud | An endothelial sprout arising from a blood vessel. (05 Mar 2000) |
| vascular bundle | Strand of vascular tissue in a plant, composed of xylem and phloem. (18 Nov 1997) |
| vascular cambium | Lateral meristem that forms the secondary tissue and is located between the xylem and phloem. (09 Oct 1997) |
| vascular capacitance | The relationship between the volume of blood contained within a segment of vasculature and the pressure distending the vascular walls over a wide range of pressures and volumes. The veins of the body are not only conduits for the return of blood to the right heart, but they also determine most of the vascular capacitance and contain most of the blood volume. Changes in vascular capacitance provide a quick and effective mechanism for the filling of the right heart, thereby influencing cardiac output. Vascular capacitance is somewhat analogous to vascular resistance but whereas vascular resistance relates to flow through a blood vessel, vascular capacitance relates to the volume contained in it. (12 Dec 1998) |
| vascular cataract | Congenital cataract in which the degenerated lens is replaced with mesodermal tissue. Synonym: cataracta adiposa, cataracta fibrosa. (05 Mar 2000) |
| vascular cell adhesion molecule-1 | Cytokine-induced cell adhesion molecule present on activated endothelial cells, tissue macrophages, dendritic cells, bone marrow fibroblasts, myoblasts, and myotubes. It is important for the recruitment of leukocytes to sites of inflammation. (12 Dec 1998) |
| vascular circle | The circle around the mouth formed by the inferior and superior labial arteries. Synonym: areolar venous plexus. (05 Mar 2000) |
| vascular circle of optic nerve | <anatomy, nerve> A network of branches of the short ciliary arteries on the sclera around the point of entrance of the optic nerve. Synonym: circulus vasculosus nervi optici, circulus arteriosus halleri, circulus zinnii, Haller's circle, Zinn's corona, Zinn's vascular circle. (05 Mar 2000) |
