diarthrózisok

Diarthrosis, also known as a synovial joint, is a type of freely movable joint in the body. These joints are characterized by the presence of a synovial cavity, which is filled with synovial fluid. This fluid acts as a lubricant, reducing friction between the articulating bones and allowing for smooth movement. The articulating surfaces of the bones within a diarthrosis are covered by articular cartilage, a smooth, resilient tissue that further minimizes wear and tear. A joint capsule, composed of fibrous connective tissue, encloses the synovial cavity and helps to stabilize the joint. The inner lining of the capsule is the synovial membrane, which produces the synovial fluid. Examples of diarthroses include the knee, hip, shoulder, and elbow joints. Their wide range of motion is crucial for activities such as walking, running, and manipulating objects. Diarthroses are essential for mobility and are found throughout the appendicular skeleton.
