There are three types of cartilages that are present in human beings. They are -Hyaline Cartilage: The matrix of hyaline cartilage is fibreless and glass-like. The matrix is also translucent in nature. They are present in costal cartilage, larynx, nasal septum and tracheal rings. This matrix helps in giving them a pliable form that is not definite in nature. They are present between the joints in the vertebral column. Collagen fibres are also present in these cartilages and these fibres help them to make sure that the joints are strong and less elastic in nature. It also makes them very less movable. Elastic Cartilage: This cartilage is present in the centre of the vertebral disc. Nucleus pulposus is the soft area that is present in them. This is believed to be the remnant part of the notochord. Calcified Cartilage: As the name suggests, the calcium ions are deposited in this type of cartilage. This helps in making them a hard type structure as that of bones.
