EHDAA2:0002140 UMLS:C1284058 EHDAA:5917 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] NCIT:C34207 metanephric bud mesonephric duct metanephric mesenchyme epithelial sac meso-epithelium epithelial layer of duct
