The renal papilla is the apex of the renal pyramid, located at the boundary between the renal medulla and the minor calices of the renal collecting system. The renal papilla contains the terminal portions of the collecting ducts of nephrons, termed papillary ducts, which transmit urine received from connecting tubules into a minor calix.
The numerous small openings of the papillary ducts on the surface of the renal papilla gives it a distinct sieve-like appearance; this part of the renal papilla is hence termed the cribriform area.
