APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Many joints have cartilage (KAHRT-uh-lij) on the ends of the bones where they come together. Healthy cartilage helps you move by allowing bones to glide over one another. It also protects bones by preventing them from rubbing against each other.

Detailed explanation-2: -Osteoarthritis occurs when the cartilage that cushions the ends of bones in your joints gradually deteriorates. Cartilage is a firm, slippery tissue that enables nearly frictionless joint motion. Eventually, if the cartilage wears down completely, bone will rub on bone.

Detailed explanation-3: -Hyaline cartilage forms the articular cartilage, covering the entire articulating surface of each bone. The articular cartilage and the synovial membrane are continuous. Some synovial joints also have associated fibrocartilage, such as menisci, between articulating bones.

Detailed explanation-4: -The use of a joint leads to wear and eventual degeneration of the cartilage that cover the bones where they meet in the joint. This loss of protective cartilage causes the joint inflammation known as osteoarthritis, as bone starts to rub directly against bone.

Detailed explanation-5: -Cells in the synovial tissue produce a small amount of clear fluid (synovial fluid), which provides nourishment to the cartilage and further reduces friction while facilitating movement.
