GENERAL HISTOLOGY

Detailed explanation-1: -The cartilage matrix is “pliable” or “jelly-like” in nature. This is because of the presence of “Aggregating GAG Chondroitin Sulphate Salt” or “Aggrecan”.

Detailed explanation-2: -The connective tissue proper is a type of connective tissue that has a jelly-like matrix in which the cells are embedded.

Detailed explanation-3: -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-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’.
