Renal pyramids

Renal pyramids (or malpighian pyramids or Malpighi's pyramids named after Marcello Malpighi, a seventeenth-century anatomist) are cone-shaped tissues of the kidney. The renal medulla is made up of 7 to 18 of these conical subdivisions (usually 7 in humans). The broad ''base'' of each pyramid faces the renal cortex, and its apex, or papilla, points internally. The pyramids appear striped because they are formed by straight parallel segments of nephrons and collecting ducts. The base of each pyramid originates at the corticomedullary border and the apex terminates in a papilla, which lies within a minor calyx, made of parallel bundles of urine collecting tubules.
