What are the hips and shoulders?

Hips and shoulders are key joints in the human body that facilitate movement and support. The hips are ball-and-socket joints connecting the pelvis to the femur, allowing for a wide range of motion in activities like walking and running. Shoulders, also ball-and-socket joints, connect the upper arm to the torso, enabling diverse arm movements. Both joints play crucial roles in maintaining balance and posture while allowing for complex physical activities.
