Which muscle is identified by the action of flexion, lateral rotation, and abduction of the hip?

The muscle that performs flexion, lateral rotation, and abduction of the hip is the sartorius. This long, thin muscle is located in the anterior compartment of the thigh. Its unique position allows it to facilitate a combination of movements.

When the sartorius contracts, it brings the thigh into a flexed position while also helping to rotate it laterally. Additionally, it plays a role in abduction, moving the thigh away from the midline of the body. This combination of actions is particularly useful in activities such as sitting cross-legged or in positions that require hip mobility.

The other muscles listed do not perform this specific combination of actions at the hip joint. For instance, the biceps femoris is primarily involved in knee flexion and hip extension but does not contribute significantly to lateral rotation or abduction. The tibialis anterior and extensor digitorum longus are mainly responsible for movements at the ankle and toes and do not influence hip motion.
