    Study Notes

    Anatomy of the Lower Limb

    • The quadriceps muscles, including the vastus intermedius, quadriceps tendon, patella, patellar ligament, and tibial tuberosity, are located in the anterior compartment of the thigh.
    • The quadriceps muscles originate from different parts of the femur and insert at the tibial tuberosity, allowing for extension of the knee joint.
    • The femoral nerve supplies the quadriceps muscles.
    • The sartorius muscle, located in the anterior compartment of the thigh, originates from the ASIS and inserts at the superior medial tibia. It is responsible for flexion and external rotation of the hip joint, as well as flexion of the knee joint.
    • The posterior compartment of the thigh includes the hamstrings, which consist of the biceps femoris, semimembranosus, and semitendinosus muscles.
    • The hamstrings are responsible for extension of the hip joint and flexion of the knee joint, as well as medial and lateral rotation of the knee joint.
    • The sciatic nerve supplies the hamstrings.
    • The medial compartment of the thigh includes the adductor muscles, including the pectineus, adductor longus, adductor brevis, and adductor magnus.
    • The adductor muscles are responsible for adduction and medial rotation of the hip joint.
    • The obturator nerve supplies most of the adductor muscles, except for the pectineus.
    • The hip joint movements include flexion (involving the rectus femoris, sartorius, and iliopsoas muscles), extension (involving the gluteus maximus and hamstrings), abduction (involving the gluteus medius and gluteus minimus), adduction (involving the adductor longus, adductor brevis, adductor magnus, pectineus, and gracilis muscles), and medial and lateral rotation (involving various muscles).
    • The femoral nerve, obturator nerve, and sciatic nerve supply the muscles of the hip joint. The femoral artery and vein supply blood to the lower limb, with the femoral artery entering the femoral triangle and passing through the adductor hiatus.
