| peripheral vascular disease | A term used to describe progressive occlusive disease of the arteries that supply the extremities. Risk factors include atherosclerosis and diabetes. (27 Sep 1997) |
|---|---|
| peripheral vascular diseases | General or unspecified diseases of the blood vessels outside the heart. It is for diseases of the peripheral as opposed to the cardiac circulation. (12 Dec 1998) |
| choroidal vascular atrophy | Atrophy affecting either all choroidal vessels or only the choriocapillaris, occurring either diffusely or confined to the posterior pole of the eye. (05 Mar 2000) |
| collagen-vascular diseases | A group of generalised disease's affecting connective tissue and frequently characterised by fibrinoid necrosis or vasculitis; in some collagen disease's, auto-immunization, particularly antinuclear antibodies, has been shown and circulating immune complexes are found. The term is not entirely acceptable because there is no evidence that collagen is primarily involved; "collagen" was once synonymous with "connective tissue" rather than describing a specific fibrinous protein in that tissue. See: connective-tissue diseases. (05 Mar 2000) |
| muscle, smooth, vascular | The nonstriated, involuntary muscle tissue of blood vessels. (12 Dec 1998) |
| skin diseases, vascular | Skin diseases affecting or involving the cutaneous blood vessels and generally manifested as inflammation, swelling, erythema, or necrosis in the affected area. (12 Dec 1998) |
| dementia, vascular | An organic mental disorder caused by systemic vascular disease such as arteriosclerotic changes in the vessels, valvular heart disease, hypertension, etc., and resulting in cerebral vascular disease with dementia. (12 Dec 1998) |
| systemic vascular resistance | An index of arteriolar compliance or constriction throughout the body; equal to the blood pressure divided by the cardiac output. (05 Mar 2000) |
| encephalotrigeminal vascular syndrome | <syndrome> Angiomatosis of the brain accompanied by nevi in the trigeminal area. See: Sturge-Weber syndrome. (05 Mar 2000) |
| endothelium, vascular | Single pavement layer of cells which line the luminal surface of the entire vascular system and regulate the transport of macromolecules and blood components from interstitium to lumen; this function has been most intensively studied in the blood capillaries. (12 Dec 1998) |
| Zinn's vascular circle | <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) |
| adenoid tissue | A structure found within the lymphatic system that consists of lymphocytes within a network of fibres. (09 Oct 1997) |
| adipose tissue | <anatomy> Connective tissue that has been specialised to store fat. See: adipocyte. (25 Jun 1999) |
| aerenchymous tissue | A type of plant tissue in which cells are unusually large, resulting in large air spaces in the plant organ, such tissues are often referred to as spongy and usually provide increased buoyancy. (09 Oct 1997) |
| areolar tissue | Loose, irregularly arranged connective tissue that consists of collagenous and elastic fibres, a protein polysaccharide ground substance, and connective tissue cells (fibroblasts, macrophages, mast cells, and sometimes fat cells, plasma cells, leukocytes, and pigment cells).
