👉 The mobile fluid, also known as synovial fluid, is a viscous, lubricating substance found within the cavities of synovial joints in the human body. It plays a crucial role in reducing friction between the articular cartilage surfaces during joint movement, thereby facilitating smooth and pain-free motion. Additionally, mobile fluid serves as a nutrient medium for the cartilage cells, providing essential nutrients and removing metabolic waste products. It also helps in shock absorption, protecting the joint from excessive stress and wear during activities. This fluid is continuously produced by specialized cells within the synovial membrane and circulated through the joint space, maintaining optimal joint function and health.
