Question

Quizplus · Accepted Answer

The hip joint has a deep, almost complete bony socket called the acetabulum that encloses the head of the femur. This structure makes the joint very stable but limits its range of motion. In contrast, the shoulder joint has a shallow socket, allowing for a greater range of motion but also making the joint more prone to dislocation. The weight of the lower limb (B), decrease in ligament and tendon attachments (C), and increase in bursae (D) can all contribute to the stability and overall function of the hip joint, but they are not the primary reason for its limited mobility compared to the shoulder joint. Therefore, the best choice is A.
