Inferior gluteal artery

  • The inferior gluteal artery (also known as sciatic artery, latin: arteria glutaea inferior) is a branch of the anterior trunk of the internal iliac artery.

    The inferior gluteal artery passes downward between the second and the third sacral segments on the sacral plexus. Then the inferior gluteal artery exits the pelvic cavity via the infrapiriform foramen, and then ramifies within the gluteal region muscles.

    The inferior gluteal artery gives off a branch to the sciatic nerve (or ischiadic nerve).

    The inferior gluteal artery supplies blood to the gluteus maximus, piriformis, internal obturatorius, gemellus superior and inferior and quadratus femoris muscles.
