Cartilage is firm but flexible supportive connective tissue in which solid matrix has fluid
filled lacunae having 1-4 living cells called chondrocytes. It forms the soft endoskeleton of
the body thereby provides support and flexibility to various body parts.
The matrix of cartilage is made up of sugars as well as protein complex chondrin which is
secreted by chondrocytes.
Cartilage occurs in nasal septum, pinna, epiglottis, larynx etc.
