Back of left lower extremity.

Nerve	sciatic nerve

The posterior fascial compartment of the thigh contains the knee flexors and hip extensors.

It consists of the following muscles:^[1][2]

• biceps femoris
• semitendinosus
• semimembranosus

The muscles here (except for the short head of the biceps femoris) are the hamstrings.
