Elastic cartilage
Elastic Cartilage
Elastic cartilage (pronunciation: /ɪˈlæstɪk ˈkɑːrtɪlɪdʒ/), also known as yellow cartilage, is a type of cartilage that provides strength and elasticity to various parts of the human body.
Etymology
The term 'elastic cartilage' is derived from the Latin words 'elasticus' meaning 'elastic' and 'cartilago' meaning 'cartilage'.
Description
Elastic cartilage is characterized by its yellowish color and high elasticity, which is due to the presence of elastin fibers. These fibers allow the cartilage to return to its original shape after being stretched or deformed.
Elastic cartilage is found in several parts of the body, including the ear, Eustachian tubes, and the epiglottis. It provides support and maintains the shape of these structures while allowing them to remain flexible.
