nivelonteloissa
Nivelonteloissa refers to the joint capsules found in synovial joints. These are tough, fibrous sacs that enclose the articular surfaces of the bones. The primary function of the nivelonteloissa is to provide structural integrity to the joint, preventing dislocation and maintaining stability. They are composed of an outer fibrous layer and an inner synovial membrane. The outer layer is made of dense connective tissue, which helps resist stretching and reinforces the joint. The inner synovial membrane, also known as the synovium, lines the joint cavity and secretes synovial fluid. This fluid acts as a lubricant, reducing friction between the articular cartilages during movement. It also nourishes the cartilage and contains phagocytic cells that remove debris from the joint. The nivelonteloissa are well-supplied with blood vessels and nerves, contributing to proprioception and pain sensation within the joint. Ligaments, which are also connective tissues, often blend with or reinforce the capsule, further enhancing joint stability. Conditions affecting the nivelonteloissa can lead to pain, swelling, and reduced mobility, such as in cases of arthritis or capsulitis.
