NEET PG DENTAL EXAM

Detailed explanation-1: -Extracellular matrix of articular cartilage. Two major load-bearing macromolecules are present in articular cartilage: collagens (mainly, type II) and proteoglycans (notably, aggrecan). Smaller classes of molecules, such as noncollagenous proteins and smaller proteoglycans, are present in smaller amounts.

Detailed explanation-2: -The cartilage is a specialized connective tissue which is compact and less vascular. It has widely spaced cells. Its extensive matrix is composed of proteins and is slightly hardened by calcium salts. Its matrix is produced and maintained by chondrocytes.

Detailed explanation-3: -Cartilage is made up of a special type of cell – chondrocytes. The solid matrix of fibrous cartilage tissue is made up of proteins and sugars.

Detailed explanation-4: -Hyaline cartilage matrix is primarily made of type II collagen and chondroitin sulphate, both of which are also found in elastic cartilage. Hyaline cartilage exists on the sternal ends of the ribs, in the larynx, trachea, and bronchi, and on the articulating surfaces of bones.
