Nivelkuoren

Nivelkuoren is a term of Finnish origin that translates to "joint capsule" in English. It refers to the fibrous sac that surrounds a synovial joint, providing structural integrity and enclosing the joint cavity. The joint capsule is composed of two layers: an outer fibrous membrane and an inner synovial membrane. The outer layer is tough and provides strength, helping to prevent dislocation of the joint. The inner synovial membrane secretes synovial fluid, a lubricating substance that reduces friction between the articular cartilages of the bones. This fluid also nourishes the cartilage and helps to absorb shock. The joint capsule plays a crucial role in the mobility and stability of joints throughout the body. Injuries to the joint capsule, such as sprains or tears, can result in pain, swelling, and a reduced range of motion. In some cases, inflammation of the joint capsule, known as capsulitis, can occur, leading to stiffness and discomfort. The structure and function of the joint capsule are vital for healthy joint performance and are a key focus in orthopedics and physiotherapy.
