Ball and socket joints offer a greater range of motion compared to hinge joints. The spherical head of one bone fits into the cup-like socket of another, enabling movements in multiple directions, including rotation, flexion, extension, abduction, and adduction.

Understanding Joint Types
The human body contains various types of joints, each designed for specific movements. Two common types are hinge joints and ball-and-socket joints, which differ significantly in their movement capabilities.
Hinge Joints
- Hinge joints are structured to allow movement primarily in one direction.
- They function like the hinges on a door, enabling flexion (bending) and extension (straightening).
- Examples include the elbow and knee joints.
Ball and Socket Joints
- Ball-and-socket joints provide a much broader range of motion.
- They consist of a spherical "ball" that fits into a "socket," allowing movement in multiple directions.
- This type of joint facilitates flexion, extension, abduction (moving away from the body), adduction (moving towards the body), and rotation.
- Examples include the shoulder and hip joints.
Range of Motion Comparison
- **Hinge Joints**: Limited movement to back-and-forth actions.
- **Ball and Socket Joints**: Allow a wider range of motion, including rotation and circular movements.
Conclusion
The correct answer is option 'C' because ball-and-socket joints indeed allow for a greater variety of movements compared to hinge joints. This flexibility is essential for activities like throwing, reaching, and rotating, which are crucial for daily activities and sports. Understanding these differences helps in recognizing how our body performs various functions efficiently.
