femoral head

The femoral head is the rounded top part of the femur, or thigh bone, which fits into the hip socket, allowing for movement in the hip joint. This ball-and-socket structure enables a wide range of motion, such as walking, running, and sitting. The femoral head is covered with cartilage, which helps it glide smoothly within the socket and absorbs shock. Proper function and health of the femoral head are crucial for mobility, and issues like fractures or arthritis can lead to pain and limitations in movement.
