What is mesonphros?
mesonphros, sometimes referred to as the middle kidney, is an organ that helps develop mammals, reptiles and birds with excretion. This body develops in all vertebrates and the excretion body remains in adulthood. In other types of animals, it only serves a temporary role and either develops in other useful structures, or recedes into the rest or unused structures, depending on the species and gender. Together with another developing kidney structure, parameesonefrotic blasto, it is considered part of the Wolffian body named for its discoverer Caspar Wolff.
Excretion is an important function for any animal that includes removal from the body of any compound that has eaten. Because of this importance, mesonephros is formed relatively early and appears for only four weeks into embryonic development in humans. Initially, the mesoderm, the type of developmental tissue, in the nephrogenic line, near the lower part of the developing spine.
This structure consists of two main sections. MesonephicCorpusCle includes bodies called vesicles where foreign compounds can enter, and S S -shaped in the S -shaped, which leads waste to the second part of the middle kidney. This area is called mesonephric or Wolffian duct and helps to exclude embryo waste.
people have different developmental fates for Mesonefros, which are conditioned by sex and runs around five months to develop. Males see that mesonephric tubules develop in the eperential or outgoing testes. Mesonephric channels turn into several components of the reproductive system, such as seedlings and vas deferens. Other parts of this structure develop into parts of the original organ known as an addition.
women have no usable structures that develop from Mesonephros. It reduces the size, instead, even if it develops in some remains in the reproductive system and the urinary tract. This is similar to the fate of this structure in other species, including Jinch of mammals, birds and reptiles where mesonphros retreats during development. Such a process occurs even faster in most other species, about six to seven weeks into development.
The presence of Mesonefros is important as a guide to development, although it is used only for a short time in many species. Studies have shown that the tissue of this structure sends chemical reports to other cells. These signals lead cells to the location of this structure, where they develop into more mature organs such as gonads.
