Liigesõõnsust

Liigesõõnsust refers to the articular cavity, the space between the articulating bones of a synovial joint. This space is filled with synovial fluid, a viscous liquid that lubricates the joint, reduces friction, and provides nourishment to the articular cartilage. The articular cavity is enclosed by the joint capsule, a fibrous sac that strengthens the joint and prevents dislocation.

The articular cartilage, a smooth, white tissue, covers the ends of the bones within the articular cavity. This cartilage absorbs shock and allows for smooth movement of the joint. The synovial membrane, a thin layer of connective tissue, lines the inner surface of the joint capsule and produces the synovial fluid.

The size and shape of the articular cavity vary depending on the specific joint and its function. For example, the hip joint has a deep articular cavity that provides stability, while the knee joint has a larger and more complex articular cavity that allows for a wide range of motion.

Problems with the articular cavity can lead to various joint conditions, such as arthritis, inflammation, and injury. These conditions can cause pain, stiffness, and reduced mobility. Diagnosis and treatment often involve imaging techniques like X-rays or MRI, as well as physical therapy and medication. Maintaining joint health through regular exercise and a balanced diet can help prevent issues related to the articular cavity.
