What lubricates and nourishes the cartilage?

What lubricates and nourishes the cartilage?

Hyaluronan is synthesized by the synovial membrane and secreted into the joint cavity to increase the viscosity and elasticity of articular cartilages and to lubricate the surfaces between synovium and cartilage.

What nourishes the chondrocytes of the articular cartilage?

Functions of synovial fluid: lubricates the articular cartilage, nourishes the chondrocytes of the articular cartilage, and acts as a shock absorber. Synovial fluid is a viscous, slippery fluid that fills all free space within the joint cavity.

What nourishes the cartilage?

Cartilage is nourished by long range diffusion from nearby capillaries in the perichondrium. Therefore, cartilage can never become very thick, as diffusion would not be sufficient to supply the cartilage with nutrients and oxygen. (This is in contrast to bone, because bone has a very good blood supply).

What is the viscous yellow fluid that nourishes and lubricates cartilage in joints called?

Synovial fluid or joint fluid is physiologic collection of lubricant fluid within a joint space. It acts as source of nutrition for surrounding structures including cartilage, meniscus, labrum etc.

How do you keep articular cartilage healthy?

Stretch every day. It will help you improve your ability to move your joints. This not only fights stiffness but also helps protect the cartilage from more wear and tear. “The more joints move, the more the cartilage gets nourished by the joint fluid,” Bush-Joseph says.

What is the function of articular cartilage?

Articular cartilage is the smooth, white tissue that covers the ends of bones where they come together to form joints. Healthy cartilage in our joints makes it easier to move. It allows the bones to glide over each other with very little friction.

What two movements are carried out when you open and close your mouth?

Direction: During depression, the mandible moves directly downwards. During elevation, it moves directly upwards. You are performing these two movements when you open and close your mouth or during mastication.
