| Name: | pronephric glomerulus |
|---|---|
| Synonyms: | pronephric glomera, pronephric glomeruli, pronephric glomus |

| Name: | glomerular endothelium fenestra |
|---|---|
| Synonyms: | GEnC fenestration, glomerular endothelial cell fenestration |
| Definition: | A large plasma membrane-lined circular pore that perforates the flattened glomerular endothelium and, unlike those of other fenestrated capillaries, is not spanned by diaphragms; the density and size of glomerular fenestrae account, at least in part, for the high permeability of the glomerular capillary wall to water and small solutes. |
