Elastic cartilage - Definition
Elastic cartilage refers to a form of cartilage that is present in the outer ear, Epiglottis and Eustachian tube.
It is also referred to by the name "Yellow Cartilage."
Elastic cartilage - Location
It can be found in the pinnae (the external ear flaps of humans and many other mammals) and the epiglottis (section of the larynx).
Elastic cartilage - Anatomy
It comprises of collagen fibers and elastic fiber networks. Elastin is the main protein in this structure. It contains many yellow elastic fibers, lying in a compact matrix, that form bundles which appear dark under microscope. These fibers are responsible for providing the elastic cartilage with improved flexibility that can help it tolerate bending repeatedly.
Elastic cartilage - Functions
The cartilage is responsible for providing support and shape to the external ear flap and the epiglottis.
