Pronephros chamber
WebIn most vertebrates, behind the pronephros where this is present, or posterior to the zone of anterior rudimentary tubules, the intermediate cell-mass is early separated from somite and lateral plate and forms the so-called nephrogenic blastema from which the remainder of the excretory organ is derived.
