Tensor fasciae latae

The tensor fasciae latae is a thin muscle situated in the gluteal region and the lateral surface of the thigh.

Action: internal rotation and abduction of the thigh, flexion and external rotation of the leg, stabilizing the hip and knee joints.

Innervation: superior gluteal nerve (L4 - S1).
