MICROANATOMY

Detailed explanation-1: -The metanephros develops from the ureteric bud and the metanephrogenic blastema. The ureteric bud forms the primitive ureter of the metanephric kidney and dilates at its upper end to become the renal pelvis, enveloped by the metanephrogenic cap.

Detailed explanation-2: -The ureteric bud, also known as the metanephric diverticulum, is a protrusion from the mesonephric duct during the development of the urinary and reproductive organs. It later develops into a conduit for urine drainage from the kidneys, which, in contrast, originate from the metanephric blastema.
