The inferior rectal artery (inferior hemorrhoidal artery) is an
arterythat supplies blood to the lower half of the anal canal.
The inferior rectal artery arises from the
internal pudendal arteryas it passes above the ischial tuberosity.
Piercing the wall of the
pudendal canal, it divides into two or three branches which cross the ischioanal fossa, and are distributed to the muscles and integument of the anal region, and send offshoots around the lower edge of the gluteus maximusto the skin of the buttock.
