Detailed explanation-1: -The main cell types in cartilage are chondrocytes, the ground substance is chondroitin sulfate, and the fibrous sheath is called perichondrium.

Detailed explanation-2: -The ground substance for hyaline cartilage is the chondroitin sulfate which is accompanied by chondrocytes and this cartilage is present throughout the body. The fibres that are found in hyaline cartilage are collagen fibres.

Detailed explanation-3: -Cartilage is a form of connective tissue in which the ground substance is abundant and of a firmly gelated consistency that endows this tissue with unusual rigidity and resistance to compression. The cells of cartilage, called chondrocytes, are isolated in small lacunae within the matrix.

Detailed explanation-4: -There is only one type of cell in cartilage, chondrocytes. They secrete and maintain the extracellular matrix of the tissue. Chondrocytes arise from mesenchymal stem cells, just like the fibroblasts of connective tissue proper do, but chondrocytes are specialized to produce just cartilage.
