Tensor fasciae latae
The tensor fasciae latae muscle is a thin muscle situated in the gluteal region and the lateral surface of the thigh.
Origin: anterior superior iliac spine, anterior aspect of the iliac crest.
Insertion: the tensor fasciae latae continues as the iliotibial tract, which inserts into the lateral condyle of the tibia.
Action: internal rotation and abduction of the thigh, flexion and external rotation of the leg, stabilizing the hip joint and knee joint.
Innervation: superior gluteal nerve (L4 - S1).
Blood supply: superior gluteal artery, lateral circumflex femoral artery.
