'

Elastic cartilage, also known as yellow cartilage, is a type of specialized connective tissue found mainly in the external ear and larynx. It is endowed with more resilience than other types of cartilage, thus giving structures containing it great flexibility.

Elastic cartilage is composed of a dense mesh of randomly oriented collagen fibers embedded in flexible proteoglycans. It is this structure that gives elastic cartilage its unique elastic properties.

In the ear, elastic cartilage is found in the upper part of the auricle, the helicoid, and the tragus. It helps maintain the shape of the external ear and allows us to move the ears to better capture sound waves. In the larynx, elastic cartilage forms the epiglottis, a flap of tissue located at the back of the throat that helps prevent food and other substances from entering the trachea.

Elastic cartilage is also found in the larynx, nose and bronchi, where it helps shape and support these structures and facilitate respiration.

Due to its elasticity, elastic cartilage is also used in joint reconstruction and the creation of artificial ears.

In summary, elastic cartilage is a type of connective tissue that forms elastic structures in the ear, larynx, nose and bronchi. It helps to maintain their shape and support respiratory functions, and is also used in joint reconstruction and the creation of artificial ears.
