The main difference between a ball joint and a socket joint lies in their structure and range of motion. A ball joint consists of a spherical end that fits into a socket, allowing for a wide range of motion in multiple directions. On the other hand, a socket joint consists of a concave surface that fits over a rounded end, allowing for a more limited range of motion in a specific direction. Ball joints are found in the shoulders and hips, providing a wide range of motion, while socket joints are found in the elbows and knees, allowing for more restricted movement. **
