The mesonephros acts as a structure similar to the kidney that, in humans, functions between the sixth and tenth weeks of embryological life. Despite the similarity in structure, function, and terminology, however, the mesonephric nephrons do not form any part of the mature kidney or nephrons.
The mesonephric duct, also known as the Wolffian duct, archinephric duct, Leydig's duct or nephric duct, is a paired organ that develops in the early stages of embryonic development in humans and other mammals.
As development proceeds, the intermediate mesoderm differentiates sequentially along the anterior-posterior axis into three successive stages of the early mammalian and avian urogenital system, named pronephros, mesonephros and metanephros respectively (anamniote embryos form only a pronephros and mesonephros).

Also called Indianite. A mineral from the lime-rich end of the plagioclase group of minerals. Anorthites are usually silicates of calcium and aluminium occurring in some basic igneous rocks, typically those produced by the contact metamorphism of impure calcareous sediments. anticline An arched fold in which the layers usually dip away from the fold axis. Contrast syncline. aphanic Having the ...
The kidney of the frog is an opisthonephros. The kidneys are seen as two elongated, red organs in this image. The opisthonephros is the functional adult kidney in lampreys (cyclostomes), most fishes, and amphibians. [1]
The most significant function of the aorta gonad mesonephros region is its role in definitive haematopoiesis. Definitive haematopoiesis is the second wave of embryonic haematopoiesis and give rise to all hematopoietic stem cells in the adult hematopoietic system.
Mesonephric tubules are genital ridges that are next to the mesonephros.. In males, some of the mesonephric kidney tubules, instead of being used to filter blood like the rest, "grow" over to the developing testes, penetrate them, and become connected to the seminiferous tubules of the testes.
The nephrogenic cord is a portion of the urogenital ridge which is the source of much of the urinary system. [1]The nephrogenic cords are bilateral condensations of the intermediate mesoderm. [2]
