The later metamorphosis of the tadpole to frog has also been studied for hormonal controls and limb development. It is surrounded by a thin, pigmented and vascular connective tissue membrane, the piamater, which is closely applied with the brain. There have also been many different species used in these developmental studies. 4. From the outer smooth convex posterior side of each kidney arises a mesonephric or Wolffian duct or ureter which passes backwards to open into dorsal side of the cloaca. It is primarily involved in assisting the frog in carrying out urine excretion and reproduction. In male frog the ureters convey the sperms and urine, and, hence, are called urinogenital ducts.
