Answer:
Synovial fluid is a viscous, clear, and lubricating fluid found within the synovial joints of the body. It plays a crucial role in the proper functioning of these joints.
Here are some key points to define synovial fluid:
Composition: Synovial fluid is primarily composed of water, which makes up around 80-90% of its content. It also contains various substances, including hyaluronic acid, proteins, electrolytes, and cells called synoviocytes.
Lubrication: One of the main functions of synovial fluid is to lubricate the surfaces of the joint, reducing friction between the bones. This allows for smooth movement and prevents wear and tear on the joint surfaces.
Shock absorption: Synovial fluid also acts as a shock absorber, helping to distribute forces and protect the joint from impact during movement. It cushions the joint, minimizing the risk of injury and damage.
