On which structure of the femur does the highlighted muscle insert?
Explanation
The highlighted muscle inserts on the gluteal tuberosity of the femur. The gluteal tuberosity is a rough, bony prominence located on the posterior aspect of the femur, specifically on the upper part of the shaft. This tuberosity serves as the attachment site for the gluteus maximus muscle, which is responsible for hip extension and lateral rotation. By inserting on the gluteal tuberosity, the gluteus maximus muscle can exert its force and contribute to the movement and stability of the hip joint.Rate this question:
