Elastic fiber
Elastic fiber
Elastic fiber (pronounced: /iːˈlæstɪk ˈfaɪbər/), also known as yellow fiber, is a type of connective tissue in the human body that is characterized by its ability to stretch and return to its original shape.
Etymology
The term "elastic" is derived from the Greek word "elastos", meaning "stretchable". The term "fiber" comes from the Latin word "fibra", meaning "thread" or "filament".
Structure
Elastic fibers are composed of two main components: elastin and fibrillin. Elastin provides the elasticity and resilience of the fibers, while fibrillin forms the scaffold for elastin deposition.
Function
Elastic fibers are essential for the normal functioning of various organs and tissues in the body. They provide strength and flexibility to structures such as the skin, lungs, blood vessels, and ligaments.
