Encyclopedia > Müllerian duct

The Müllerian ducts are paired ducts of the embryo which empty into the cloaca, and which in the female develop into the upper vagina, cervix, uterus and oviducts; in the male they disappear except for the vestigial vagina masculina and the appendix testis. Embryos (and one tadpole) of the wrinkled frog (Rana rugosa you beezie). ... In zoological anatomy, a cloaca is the posterior opening that serves as the only such opening for the intestinal, urinary, and genital tracts of certain animal species. ... Human female internal reproductive anatomy The vagina (from the Latin for sheath or scabbard ) is the tubular tract leading from the uterus to the exterior of the body in female mammals, or to the cloaca in female birds and some reptiles. ... Categories: Anatomy stubs | Reproductive system | Gynecology ... Female internal reproductive anatomy The uterus or womb is the major female reproductive organ of most mammals, including humans. ...

The development of the Müllerian ducts is controlled by the presence or absence of the anti-Müllerian hormone (AMH) (also called Müllerian inhibiting factor (MIF) or Müllerian inhibiting hormone (MIH)). During embryogenesis of a male the testes produces AMH and as a result the development of the Müllerian ducts is inhibited. In contrast, during female embryogensis, the absence of AMH results in the develeopment of female reproductive organs, as noted above. Disturbance in the development may result in uterine absence (Mullerian agenesis) or uterine malformations. Anti-Müllerian hormone (AMH) is a dimeric glycoprotein that inhibits the development of the Müllerian ducts in a male embryo. ... AMH may stand for: Abington Memorial Hospital (amh. ... Embryogenesis is the process by which the embryo is formed and develops. ... Human male anatomy The testicles, known medically as testes (singular testis), are the male generative glands in animals. ... Mullerian agenesis refers to a condition in a female where the mullerian ducts fail to develop and a uterus will not be present. ... A uterine malformation is the result of an abnormal development of the Mullerian duct(s) during embryogenesis. ...

The Müllerian ducts are also referred to as paramesonephric ducts. They are named after Johannes Peter Müller, a physiologist who described these ducts in his text "Bildungsgeschichte der Genitalien" in 1830. Johannes Peter Müller (July 14, 1801, Koblenz - April 28, 1858, Berlin), was a German physiologist, comparative anatomist, and ichthyologist not only known for his discoveries but also for his ability to synthesize knowledge. ... Physiology (in Greek physis = nature and logos = word) is the study of the mechanical, physical, and biochemical functions of living organisms. ... 1830 was a common year starting on Friday (see link for calendar). ...
