Muscles that act on the Anterior Thigh

Several muscles act on the anterior thigh. They originate from the pelvis and extend over the hip and sometimes the knee joint to perform mainly flexion and adduction of the thigh.

Some of these muscles are anterior thigh muscles in the sense that they are both located there and act on it. Others are located more proximally at the pelvic region while still acting on the anterior thigh.

Hip flexion is mainly achieved by the iliopsoas muscle, supported by the quadriceps femoris muscle.

Hip adduction is performed by the adductor magnus, adductor longus, adductor brevis and adductor minimus, as well as the pectineus muscle.

The tensor fasciae latae muscle supports the gluteal muscles with the abduction of the thigh in the hip joint. It also stabilizes both the hip and knee joints.
