OpenCyc:Mx4rvhmm6JwpEbGdrcN5Y29ycA The duct of amniotes that carries urine from a metanephric kidney to the urinary bladder. [Bemis_WE, Functional_Anatomy_of_the_Vertebrates:_An_Evolutionary_Perspective, Glossary_G-29, Grande_L, Liem_KF, Third_Edition_(2001)_Orlando_Fla.:_Harcourt_College_Publishers, Walker_WF][VHOG] The first embryonic hint of a metanephros is the formation of the metanephric duct that appears as a ureteric diverticulum arising at the base of preexisting mesonephric duct. The ureteric diverticulum grows dorsally into the posterior region of the nephric ridge. Here it enlarges and stimulates the growth of metanephric tubules that come to make up the metanephric kidney. The metanephros becomes the adult kidney of amniotes, and the metanephric duct is usually called the ureter.[well established][VHOG] UBERON:0000056 UMLS:C0041951 VHOG:0000605 XAO:0000144 galen:Ureter in humans, consists of adventitial, muscular and mucoa layers metanephric duct uberon ureteral ureteric mesoderm-derived structure abdominal segment element excretory tube lateral structure
