The ureteric bud is a protrusion from the mesonephric duct during the development of the urinary and reproductive organs. It later develops into the adult kidney, except for the nephrons, which, in contrast, originate from the metanephric blastema.
It is also sometimes called the "mesonephric diverticulum".
Famous quotes containing the word bud:
“Language is a living thing. We can feel it changing. Parts of it become old: they drop off and are forgotten. New pieces bud out, spread into leaves, and become big branches, proliferating.”
—Gilbert Highet (1906–1978)
