Because there is no indication of what's the highlighted structure I'm going to tell you where all the four muscles of the quadriceps femoris originate from.
The vastus lateralis originates on the greater trochanter and the lateral lip of linea aspera. The vastus intermedius originates on the lateral and anterior surfaces of the femur's body. The vastus medialis originates on the medial lip of the linea aspera and the intertrochanteric line. Rectus femoris originates, superior to the acetabulum, on the ilium.

The vastus medialis originates on the medial lip of the linea aspera and the intertrochanteric line. Rectus femoris originates, superior to the acetabulum, on the ilium.
Quadriceps muscles are involved in hip flexor and knee extensor. Quadriceps muscles are made up of four individual muscles, which are three vastus muscles and rectus femoris. These muscles collectively are the strongest muscles in the body. The muscles are found in the anterior regions of the thigh.
The four muscles of quadriceps work collectively to allow walking, running, and standing. These muscles have different originate points, such as:
1. Vastus lateralis originates from the lateral hip of linea aspera on the greater trochanter.
2. Vastus intermedius originates from the anterior and lateral surfaces of femur.
3. Vastus medialis originates from the medial lip of linea aspera.
4. Rectus femoris originates from the superior of the acetabulum on the ilium.
Therefore, the four quadriceps muscles are three vastus and rectus femoris. These muscles have different originate pathway.
