Synovial fluid, also called synovia, is a viscous, non-Newtonian fluid found in the cavities of synovial joints.With its egg white–like consistency, [1] the principal role of synovial fluid is to reduce friction between the articular cartilage of synovial joints during movement. [2]
The water of synovial fluid is not secreted as such but is effectively trapped in the joint space by the hyaluronan. The macrophage-like synovial cells (derived from monocytes in blood) [3] are responsible for the removal of undesirable substances from the synovial fluid (hence are rich in Golgi apparatus). It accounts for approximately 25% of ...
The synovial cavity/joint is filled with synovial fluid. The joint capsule is made up of an outer layer of fibrous membrane, which keeps the bones together structurally, and an inner layer, the synovial membrane, which seals in the synovial fluid. They are the most common and most movable type of joint in the body of a mammal.
This final structure will form several distinct layers of the articular cartilage found in all synovial joints including the deep zone (closest to the bone), middle zone, and superficial zone (closest to the synovial fluid). Maintenance of articular cartilage is guided by a balance of anabolic (cartilage generating) [10] [11] and catabolic ...
The capsule and fluid protect the cartilage, muscles, and connective tissues. With osteoarthritis, the cartilage becomes worn away. Spurs grow out from the edge of the bone, and synovial fluid increases.
A synovial bursa, usually simply bursa (pl.: bursae or bursas), is a small fluid-filled sac lined by synovial membrane with an inner capillary layer of viscous synovial fluid (similar in consistency to that of a raw egg white). It provides a cushion between bones and tendons and/or muscles around a joint. This helps to reduce friction between ...
an inner (synovial membrane, synovial stratum) which is a secreting layer; On the inside of the capsule, articular cartilage covers the end surfaces of the bones that articulate within that joint. The outer layer is highly innervated by the same nerves which perforate through the adjacent muscles associated with the joint.
The compression of the articular cartilage or flexion of the elastic cartilage generates fluid flow, which assists the diffusion of nutrients to the chondrocytes. Compared to other connective tissues, cartilage has a very slow turnover of its extracellular matrix and is documented to repair at only a very slow rate relative to other tissues.
