The superior and inferior gemelli muscles are located within the gluteal region in the lower limb. They are narrow and triangular-shaped, separated by the obturator internus tendon.

  • Attachments:
    • Superior gemellus muscle originates from the ischial spine
    • Inferior gemellus muscle originates from the ischial tuberosity.
    • They both attach onto the greater trochanter of the femur.
  • Actions: Lateral rotation and abduction.
  • Innervation:
    • Superior gemellus muscle is innervated by the nerve to obturator internus
    • Inferior gemellus is innervated by the nerve to quadratus femoris.
  • Blood Supply: Inferior gluteal artery
