Explanation:
Detailed explanation-1: -The ureteric bud arises from the mesonephric duct and progresses laterally to invade the metanephrogenic blastema (precursor of the mature kidney). The caudal end of the mesonephric duct (past the ureteric bud is called the common excretory duct.
Detailed explanation-2: -There are two embryonic kidney precursors, the pronephros and mesonephros. Remarkably, these precursors take form and then involute and yet are necessary for development of the definitive kidney, as interruption of their development results in renal agenesis.
Detailed explanation-3: -Derivatives of the ureteric bud: Collecting tubules and ducts. Minor and major calyces. Ureters.
