Tensor Fascia Lata - Podcast Version 0:00 / 0:00 1x 0.25x 0.5x 0.75x 1x 1.25x 1.5x 1.75x 2x The tensor fascia lata is a muscle of the gluteal region in the lower limb. It is a small superficial muscle which lies towards the anterior edge of the iliac crest. It functions to tighten the fascia lata, and so abducts and medially rotates the lower limb. Attachments: Originates from the anterior iliac crest, attaching to the anterior superior iliac spine (ASIS). It inserts into the iliotibial tract, which itself attaches to the lateral condyle of the tibia. Actions: Abduction and medial rotation of the lower limb. Innervation: Superior gluteal nerve. Blood Supply: Superior gluteal artery. By TeachMeSeries Ltd (2026) Fig 1The tensor fascia lata and iliotibial tract.

Learn More Frequent questions What is the function of the tensor fascia lata muscle? The tensor fascia lata muscle primarily functions to abduct and medially rotate the lower limb. It achieves this by tightening the fascia lata, which supports the lateral aspect of the thigh. Where does the tensor fascia lata muscle originate and insert? The tensor fascia lata originates from the anterior iliac crest and the anterior superior iliac spine (ASIS). It inserts into the iliotibial tract, which connects to the lateral condyle of the tibia. What is the innervation of the tensor fascia lata? The tensor fascia lata is innervated by the superior gluteal nerve. This nerve supplies the muscle, enabling its motor functions. What is the blood supply for the tensor fascia lata? The blood supply to the tensor fascia lata muscle comes from the superior gluteal artery. This artery ensures adequate oxygenation and nutrients for the muscle's activity. How does the tensor fascia lata contribute to lower limb movement? The tensor fascia lata contributes to lower limb movement by facilitating abduction and medial rotation. Its action is essential for activities such as walking and stabilising the pelvis during movement. Rate This Article
