Ureter develops from:

The ureter develops from the Metanephric Diveiculum (Ureteric bud) which arises as a diveiculum from the Mesonephric (Wolffian duct). Permanent kidneys develop in the Metanephros near the caudal end of the Nephrogenic cord from two sources. Metanephric Diveiculum (Ureteric bud) Metanephric mesoderm The ureteric bud or metanephric diveiculum is an outgrowth from the mesonephric duct near its entrance into the cloaca Each newly formed ureteric bud is covered at its distal end by a metanephric tissue cap. The metanephric mesoderm is derived from the caudal pa of the nephrogenic cord The ureteric bud grows to give rise to the ureter renal pelvis, major and minor calyces and approximately 1 to 3 million collecting tubules The metanephric mesoderm gives rise to the nephron (Nephron consists of glomeruli, glomerular capsule, proximal convoluted tubule, loop of henle and distal convoluted tubule Ureter Renal pelvis Major calyx Minor calyx Collecting duct Distal convoluted tubule Loop of Henle Proximal convoluted tubule Renal (Bowman&;s) capsule Renal glomerulus Ref: Moore&;s The developing human 7th edition Pgno: 288
