Posterior compartment of thigh

Cross-section through the middle of the thigh. (Posterior compartment is at center bottom.)

Back of left lower extremity.
Latin	compartimentum femoris posterius
Gray's	subject #128 478
Artery	inferior gluteal artery, profunda femoris artery, perforating arteries
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]

The muscles here (except for the short head of the biceps femoris) are the hamstrings. These muscles are mainly innervated by the sciatic nerve , specifically the tibial nerve. The short head of the biceps femoris is innervated by the fibular nerve.
