Bursa

A bursa (plural: bursae) is a small, fluid-filled sac that acts as a cushion between bones and tendons, muscles, or skin. It reduces friction and allows for smooth movement in joints. These sacs are lined with a synovial membrane, which secretes synovial fluid, a lubricant that further minimizes friction. Bursae are located throughout the body, particularly near joints, where they facilitate efficient and painless motion. They protect these areas from the constant friction caused by movement. Inflammation of a bursa is called bursitis, a common condition often caused by overuse or repetitive motion. Careful diagnosis and treatment are necessary to manage this ailment and promote healing.
