Name: pronephros
Synonyms: embryonic kidney, pronephric nephron

Name: pronephric glomerular basement membrane
Synonyms: pronephric glomerular filtration membrane
Definition: Membrane between the pronephric podocytes and the pronephric glomerular capillaries. It is a trilaminar structure composed of the fused basement membranes of the glomerular capillaries and basement membrane of the podocytes. The capillary membranes touch the GBM at contact points that are separated by pores. The membrane is semi-permeable allowing water and small molecules to pass into the renal capsular space.
