Anterior compartment of thigh

From Wikipedia, the free encyclopedia

Anterior compartment of thigh
Cross-section through the middle of the thigh. (Anterior compartment is at upper left.)
Artery	femoral artery
Nerve	femoral nerve

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.

The leg extension is an isolation exercise.
