Joints are cushioned and supported by soft tissues that prevent your bones from rubbing against each other. A connective tissue called articular cartilage which plays an important role. It helps joints move smoothly without friction or pain.

Some joints have a synovial membrane, a padded pocket of fluid that lubricates joints. Many joints, such as elbow, knee etc, are supported by tendons and ligaments. Tendons connect muscles to your bones, while ligaments connect bones to other bones.
