👉 Bone fluid, also known as synovial fluid, is a vital component of the joint cavity within bones, particularly in synovial joints. It serves multiple crucial functions: it lubricates the joint surfaces to reduce friction and wear during movement, nourishes the cartilage that lines the joint, and removes waste products from the cartilage. This fluid is produced by the synovial membrane lining the joint and consists mainly of water, but also contains proteins, electrolytes, and hyaluronic acid, which contribute to its viscosity and lubricating properties. Overall, bone fluid is essential for maintaining joint health and facilitating smooth, pain-free movement.
