Greater occipital N

Occipital A

lateral to greater occipital N

Accessory N- innervates trapezius can be seen on trapezius muscle

Gluteus maximus M

What is its association with the iliotibial tract and femur?

Located on the lateral edge of the fascia lata, the iliotibial tract forms a wide sheath of fibrous connective tissue that surrounds the lateral thigh. It arises at its proximal end from the tendons of the tensor fasciae latae and gluteus maximus muscles.
