Anatomical terminology |
The ureteric bud, also known as the metanephrogenic 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.
It is also sometimes called the "mesonephric diverticulum".

- BACKGROUND: Specification of the metanephric mesenchyme is a central step of kidney development as this mesenchyme promotes nephric duct induction to form a ureteric bud near its caudal end. Before ureteric bud formation, the caudal nephric duct swells to form a pseudostratified epithelial domain th
