'''Intermediate mesoderm''' is a type of [[mesoderm]] that is located between the [[paraxial mesoderm]] and the [[lateral plate]].
It develops into the part of the [[urogenital system]] ([[kidney]]s and [[gonad]]s)
* forms of urogenital system
* series of short evaginations from each segment grows dorsally caudally
* vestiges of the future [[kidney]], the [[pronephros]] briefly appears.
* [[pronephric duct]] arises in the intermediate mesoderm just ventral to the anterior [[somite|somites]]
* grows caudally until it becomes the [[cloaca]].
*it is distinct from the lateral mesoderm, as it is not influenced by the secretion of [[BMP-4]] by the [[ectoderm]], possibly due to the lack of [[protein receptor|receptors]].
