Anterior compartment

This contains the flexors of the hip, and extensors of the knee, such as the quadriceps femoris. These muscles are supplied by the femoral nerve Femoral nerve

and the femoral artery. The longest muscle in the Human body, the Sartorius muscle, runs through here.

Medial compartment

The obturator nerve supplies the hip adductors in this compartment. Muscles include adductor longus, adductor brevis and gracilis.

Posterior compartment

The muscles here are the hamstrings. These muscles flex the knee, and extend the hip. This compartment is sciatic nerve territory.

Blood vessels

The arterial supply is by the femoral artery and the obturator system. The lymphatic drainage closely follows the arterial supply.
