 A group of muscles that (mostly) act to
extend the lower limb at the knee joint
 They are innervated by the femoral nerve ,
and receive arterial supply from the femoral
artery.

7. Medial compartment
 Known as the hip adductors
 They are innervated by the obturator nerve ,
and receive arterial supply from the
obturator artery.

8. Posterior compartment
 Known as the hamstrings.
 act to extend at the hip, and flex at the knee
 They are innervated by the sciatic nerve ,
and receive arterial supply from the
profunda femoris artery.
