Which bony landmark is located at the back of the pelvis and serves as an attachment point for the sacroiliac ligaments?
Posterior Superior Iliac Spine (PSIS)
What is the function of the adductor muscles in the hip?

Why is it important to stretch both sides of the body equally?
To maintain balanced flexibility and prevent imbalances that could lead to injury.
What is the role of the gluteus medius during lateral pelvic tilt?
The gluteus medius helps stabilize the pelvis during lateral pelvic tilt, preventing excessive dropping of the pelvis on the unsupported side.
Where does the gluteus medius originate?
