part_of starts_at ends_at male reproductive system paramesonephric duct paramesonephric duct of male EMAPA:35661 Mullerian duct of male The paramesonephric duct of male (pnd) (syn: Mullerian duct of male) (TS:20-TS:24 in males). Paired epithelial ducts which develop laterally adjacent to the nephric ducts in the anterior mesonephros and extend caudally down the rostro-caudal length of the nephric ducts to terminate at the urogenital sinus/pelvic urethra. Part of the reproductive system. They connect at the caudal end, to the dorsal, anterior urogenital sinus (caudal urogenital sinus) at the urogenital sinus ridge at TS:21, crossing over the nephric ducts, such that they connect to the urethra medially, with the nephric ducts located on either side. The ducts are marked by Cdh1 and Pax2. They are comprised of epithelium and mesenchyme of paramesonephric duct of female. The epithelium is marked by Cdh1 and Pax2. Derives from the paramesonephric duct (syn: Mullerian duct, TS:19). In males from TS:22, the ducts begin to degenerate with only remnants of the ducts present at TS:24 in males. anatomical_structure TS20 TS23
