Muscles of the lower limb helps in the extension of lower leg and stabilize the patella.

Explanation:

Muscles of the lower limb and their functions-

  • Sartorius- a thin muscle in the thigh which originates from the pelvis and attaches to the tibia. It helps in flexing of the lower leg at the knee joint.
  • Pectineus muscle helps in hip flexion.
  • Quadriceps muscle group has four muscles.  All four muscles are the key extensors of the lower leg at the knee joint. These muscles also stabilize and protect the patella.  
  • Articularis genu muscle is a small flat muscle present at the anterior knee. During knee extension it acts to tighten the synovial membrane and prevents impingement of the synovial folds between the femur and the patella.
