Bones meet at joints, which come in three types: synarthroses (immovable, like in the skull), amphiarthroses (slightly movable, like vertebral joints), and synovial joints (highly movable, like shoulders and hips). Synovial joints are lubricated by synovial fluid and lined by articular cartilage. Overuse can lead to arthritis, causing pain and stiffness.
