par·a·mes·o·neph·ric duct

either of the two paired embryonic ducts extending along the mesonephros roughly parallel to the mesonephric duct and emptying into the cloaca; in the female, the upper parts of the ducts form the uterine tubes, whereas the lower fuse to form the uterus and part of the vagina; in the male, vestiges of the ducts form the prostatic utricle and the appendix testis.

Müllerian duct

An embryonic structure that, in females, develops into the ducts of the reproductive system. The Müllerian duct degenerates in the male under the influence of the protein Müllerian inhibiting substance. (Johannes Peter Müller, German physiologist and comparative anatomist, 1801–58).

Mullerian duct

the duct from the embryonic PRONEPHROS which in later development in mammals becomes the oviduct in females and disappears in males. It is named after the German anatomist and physiologist Johannes Müller (1801–58).
