In anatomy, what is a common characteristic of synovial joints?

Synovial joints are distinguished by their ability to provide a wide range of motion, which is referred to as free movement. This characteristic is a result of their unique anatomical structure, which includes a synovial cavity filled with synovial fluid that lubricates the joint, facilitating smooth movement. The presence of articular cartilage covering the ends of the bones further reduces friction, allowing for flexibility and a higher degree of mobility compared to other types of joints, such as fibrous or cartilaginous joints, which are typically more restrictive. This distinctive feature enables synovial joints to perform various movements, including rotation, gliding, and bending, making them essential for locomotion and overall flexibility in the body.
