| glomerulonephritis, membranoproliferative | Chronic glomerulonephritis characterised histologically by proliferation of mesangial cells, increase in the mesangial matrix, and a thickening of the glomerular capillary walls. The wall thickening is sometimes said to be a result of the interposition of mesangial cytoplasm or matrix between the basement membrane and the endothelium of the capillary wall. It is often divided into types I and II, and sometimes III. Pathogenesis is not well understood, but some types are thought to involve the immune system, with the complement system, in particular, being implicated. (12 Dec 1998) |

| glomerulonephritis, membranous | A disease of the glomerulus manifested clinically by proteinuria, and sometimes by other features of the nephrotic syndrome. It is histologically characterised by deposits in the glomerular capillary wall between the epithelial cell and the basement membrane and a thickening of the membrane. Also characteristic are outward projections of the membrane between the epithelial deposits in the form of "spikes". There is some agreement that the deposits are antigen-antibody complexes.

| glomerulopathy | Glomerular disease of any type. Origin: Glomerulus + G. Pathos, suffering (05 Mar 2000) |
| glomerulosa cell | A cell of the zona glomerulosa of the adrenal cortex that is the source of aldosterone; the cell's are arranged in spherical or oval groups. (05 Mar 2000) |
| glomerulosclerosis | Hyaline deposits or scarring within the renal glomeruli, a degenerative process occurring in association with renal arteriosclerosis or diabetes. Synonym: glomerular sclerosis. Origin: Glomerulus + G. Sklerosis, hardness (05 Mar 2000) |
| glomerulosclerosis, focal | Glomerular disease characterised by focal and segmental areas of glomerular sclerosis, usually commencing in the juxtamedullary glomeruli and gradually spreading to involve other parts of the kidney, with eventual kidney failure. (12 Dec 1998) |
| glomerulose | <nephrology> Pertaining to or of the nature of a glomerulus, especially a renal glomerulus. (14 Oct 1997) |
| glomerulus | <anatomy, nephrology> One of the structures which comprise the nephron (functional unit) in the kidney. The glomerulus is composed of capillary blood vessels which are actively involved in the filtration of the blood. (27 Sep 1997) |
| glomerulus of mesonephros | One of the tufts of capillary vessels within the mesonephros derived from a lateral branch of the primary aorta; each glomerulus is connected to a tubule. (05 Mar 2000) |
| glomerulus of pronephros | One of the tufts of capillary vessels in the pronephros derived from a lateral branch of the aorta. (05 Mar 2000) |
| glomiform glands | 1. A small globular body. 2. A highly organised arteriolovenular anastomosis forming a tiny nodular focus in the nailbed, pads of the fingers and toes, ears, hands, and feet and many other organs of the body. The afferent arteriole enters the connective tissue capsule of the glomus, becomes devoid of an internal elastic membrane, and develops a relatively thick epithelioid muscular wall and small lumen; the anastomosis may be branched and convoluted, richly innervated with sympathetic and myelinated nerves, and connected with a short, thin-walled vein that drains into a periglomic vein and then into one of the veins of the skin. The glomus functions as a shunt-or bypass-regulating mechanism in the flow of blood, temperature, and conservation of heat in the part as well as in the indirect control of the blood pressure and other functions of the circulatory system. Synonym: glandulae glomiformes, glomiform glands, glomus body. Synonym: glome. Origin: L. Glomus, a ball (05 Mar 2000) |
| glomuliferous | <biology> Having small clusters of minutely branched coral-like excrescences. Origin: L. Glomus a ball. Source: Websters Dictionary (01 Mar 1998) |

| glomus caroticum | A small cluster of chemoreceptive and supporting cells located near the bifurcation of the internal carotid artery. The carotid body, which is richly supplied with fenestrated capillaries, senses the pH, carbon dioxide, and oxygen concentrations in the blood and plays a crucial role in their homeostatic control.
