The substance that makes the cartilage at the end of the bones slippery is called synovial fluid. This viscous fluid is produced by the synovial membrane and serves to lubricate the joints, reduce friction during movement, and provide nourishment to the cartilage. The combination of cartilage and synovial fluid allows for smooth and pain-free joint motion.
mucus
No, but they have cartilage. That's what makes the Earthworm move!
A lubricant is a substance, such as oil or grease, that makes things slippery.
cartilage
The ends of the bones are covered with a tough elastic tissue called cartilage. cartilage makes the ends of the bones smooth and reduces friction between the bones during movement cartilage is also present in various other parts of our body . you could feel cartilage in the upper part of your ear and in the front part of your nose . these parts are not as hard as bones and can bend
Cartilage does not contain bones nor is bone. Cartilage is soft to moderately hard tissue that makes your ear lobes, tips of your nose, joints between bones, and more more objects in your body.
Most fish have bones. Sharks and rays do not have bones but they do have bone-like structures that are made from cartilage.
The end of bones are covered with a smooth, slippery, thick layer of tissue called CARTILAGE.WHY?Because it is flexible and important in joints because it acts as a shock absorber.It also makes movement easier. HOW? (how does it make movement easier?)By reducing friction that would be caused by bones rubbing together.Also a special tissue called Periosteum
The external ear itself has no bones, only cartilage.
Cartilage is made up of specialized cells called chondrocytes embedded in an extracellular matrix composed of collagen fibers, proteoglycans, and water. This matrix gives cartilage its firm yet flexible structure, allowing it to provide cushioning and support in various parts of the body.
i don't really think that they have bones its more like cartilage, the stuff that makes up your nose i believe
1) bones 2) cartilage 3) tendons 4) ligaments
