Intermediate mesoderm

It develops into the part of the urogenital system (kidneys and gonads)

• 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 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 receptors.
