Synovial joint

A synovial joint is a type of joint in the body that allows for smooth and flexible movement between bones. It is characterized by a fluid-filled capsule called the synovial cavity, which contains synovial fluid that lubricates the joint to reduce friction. These joints are supported by surrounding structures like cartilage, ligaments, and muscles, providing stability while enabling movements such as bending, rotating, and sliding. Common examples include the knee, elbow, and shoulder, all of which are crucial for everyday activities and mobility.
