'Intermediate mesenchyme or intermediate mesoderm is a type of embryological tissue called mesoderm that is located between the paraxial mesoderm and the lateral plate.
It develops into the part of the urogenital system (kidneys and gonads), as well as the reproductive system.
- 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.
Famous quotes containing the word intermediate:
“Complete courage and absolute cowardice are extremes that very few men fall into. The vast middle space contains all the intermediate kinds and degrees of courage; and these differ as much from one another as men’s faces or their humors do.”
—François, Duc De La Rochefoucauld (1613–1680)
