NEET BIOLOGY

Detailed explanation-1: -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-2: -The cartilage matrix is composed of collagens (primarily type II collagen with minor collagen types IX and XI) and proteoglycans. Although a number of proteinases have been found in the arthritic joints (Nagase and Woessner, 1993), matrixins are considered to be key enzymes for the degradation of cartilage matrix.

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: -What is cartilage made of? Cartilage a strong and smooth substance made up of “chondrocytes, ” or specialized cartilage cells, that produce a matrix of collagen, proteoglycans (a special type of protein) and other non-collagenous proteins.

Detailed explanation-5: -Cartilage contains numerous noncollagenous proteins in its extracellular matrix, including proteoglycans. At least 40 such molecules have been identified, differing greatly in structure, distribution, and function.
