What is the difference between meso and metanephric kidney?
Answers
Answer:
Definition of metanephros. : either member of the final and most caudal pair of the three successive pairs of vertebrate renal organs that functions as a permanent adult kidney in reptiles, birds, and mammals but is not present at all in lower forms — compare mesonephros, pronephros.
Explanation:
Explanation:
Mesonephros develops by the formation of mesonephric tubules from the intermediate mesoderm, it is the principal excretory organ during early embryonic life (4—8 weeks). It gradually degenerates, although parts of its duct system become associated with the male reproductive organs.
Metanephros arises caudal to the mesonephros at five weeks of development; it is the permanent and functional kidney in higher vertebrates. It is derived from the intermediate mesoderm. The ureteric bud arises as a diverticulum from the Wollfian duct, close to the entrance to the cloaca and grows towards and inside the metanephric mesenchyme.
