in taxon glomerular endothelium fenestra glomerular endothelial cell fenestration bf 2011-12-12T10:53:24Z GEnC fenestration cellular_component 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.
