Muscles and tendons

Muscles, bursae, tendons and bones must be healthy and function properly for the body to move normally. The muscles, which contract to produce movement, connect to the bones through the tendons. Bursae are flattened pockets that contain joint (synovial) fluid. They reduce friction in areas where the skin, muscles, tendons and ligaments slide over the bones.

Often, muscles, bursae and tendons are injured during sports activities. Injuries, overuse, infections and, occasionally, illnesses can cause temporary or permanent damage to these structures. The damage can cause pain, limit movement control and reduce the normal range of motion.
