The vastus lateralis muscle lies superficial to the biceps femoris muscle with its lateral side covered by the tensor fasciae latae. The muscle lies medial to the gluteus maximus and is situated lateral to the vastus intermedius muscle.
The vastus lateralis provides the extension of the leg at the knee joint.
The vastus lateralis receives arterial blood supply from the ascending, transverse and descending branches of the lateral circumflex femoral artery and the lateral artery, a perforating branch of the deep femoral artery.
