  1. Biceps femoris
    O: The sacrotuberous ligament and the ischiatic tuberosity.

    • INSERTION: By means of the fascia lata and crural fascia to the patella, patellar ligament, and cranial border of the tibia; by means of the crural fascia to the subcutaneous part of the tibial body; the tuber calcanei.

    • ACTION: To extend the hip, stifle, and hock.The caudal part of the muscle flexes the stifle.
    • INNERVATION: Sciatic nerve.
  2. Semitendinosus
    • ORIGIN: The ischiatic tuberosity.
    • INSERTION: The disto-cranial border of the tibia. The medial surface of the body of the tibia and the tuber calcanei by means of the crural fascia.
    • ACTION: To extend the hip, flex the stifle, and extend the hock.
    • INNERVATION: Sciatic nerve.
  3. Semimembranosus
    • ORIGIN: The ischiatic tuberosity.
    • INSERTION: The distal medial lip of the caudal rough surface of the femur and the medial condyle of the tibia.
    • ACTION: To extend the hip. The part that attaches to the femur extends the stifle; the part that attaches to the tibia flexes or extends the stifle, dependin gon the position of the limb.
    • INNERVATION: Sciatic nerve.
  4. Sartorius
    • ORIGIN: Cranial part—the crest of the ilium and the thoracolumbar fascia; caudal part—thec ranial ventral iliac spine and the adjacent ventral border of the ilium
    • INSERTION: Cranial part—the patella, in common with the rectus femoris of the quadriceps;caudal part—the cranial border of the tibia, in common with the gracilis.
    • ACTION: To flex the hip. The cranial part extends the stifle; the caudal part flexes the stifle.
    • INNERVATION: Femoral nerve.
  5. Gracilis
    • ORIGIN: The pelvic symphysis by means of the symphysial tendon.
    • INSERTION: The cranial border of the tibia and, with the semitendinosus, the tuber calcanei.
    • ACTION: To adduct the limb, flex the stifle, and extend the hip and hock.
    • INNERVATION: Obturator nerve.
  6. Pectineus
    • ORIGIN: From the iliopubic eminence and the pubic tubercle via the prepubic tendon.
    • INSERTION: The distal end of the medial lip of the caudal rough face of the femur.
    • ACTION: To adduct the limb.
    • INNERVATION: Obturator nerve.
  7. Adductor
    • ORIGIN: The entire pelvic symphysis by means of the symphysial tendon, the adjacent part of the ischiatic arch, and ventral surface of the pubis and ischium.
    • INSERTION: The entire lateral lip of the caudal rough face of the femur.
    • ACTION: To adduct the limb and extend the hip.
    • INNERVATION: Obturator nerve.
