GENERAL HISTOLOGY

Detailed explanation-1: -The cartilage matrix is composed of collagens (primarily type II collagen with minor collagen types IX and XI) and proteoglycans.

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: -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-4: -The matrix of the cartilage is secreted by the immature type of cells called chondroblasts. When this matrix surrounds the chondroblasts, the cells become chondrocytes. So, the correct answer is ‘Chondroblasts’.

Detailed explanation-5: -The solid matrix of cartilage is composed of proteins and sugars.
