Anterior compartment of thigh

The anterior fascial compartment of thigh contains the knee extensors and hip flexors:
 * sartorius (the longest muscle in the human body)
 * quadriceps (rectus femoris, vastus lateralis, vastus intermedius, vastus medialis)
 * articularis genu

The iliopsoas is sometimes considered a member of this group; however, it does not share the same innervation.
