Rectus Femoris

Diagram of anterior muscles. Diagram of posterior muscles.

The rectus femoris muscles are among the quadriceps muscles located in the upper anterior (anterior = 'front') of each of the legs of the human body.

The four quadriceps muscles are the:

  • rectus femoris - along the middle of the thigh
  • vastus lateralis - lateral side of the femur (outer side of the thigh)
  • vastus medialis - medial side of the femur (inner part thigh)
  • vastus intermedius - between the vastus lateralis and the vastus medial is on the front of the femur (top / front of the thigh), beneath the rectus femoris

Of these the rectus femoris is the only muscle that crosses the hip joint. An example of when the rectus femoris muscle is used is when kicking a ball.
