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:
“the bud packed
tight with its miracle swayed
stiffly on breaths
of air, moved
as though impelled
by stirrings within itself.”
—Robert Earl Hayden (1913–1980)
