Cartilage is largely composed of water and contains no nerves or blood vessels. There are three types of cartilage.
Hyaline cartilage provide support with flexibility and resistance.
It is the most abundant cartilage. Hyaline cartilage is the cartilage that covers bone at movable joints, connects the ribs to the sternum, forms the larynx or voice box, reinforces the passageways of the respiratory system, and forms the end of the nose. Elastic cartilage is found in only two locations. It forms the external ear and the epiglottis. It is able to stretch and bend repetitively without braking or tearing.
