ELASTIC CARTILAGE Meaning and
Definition
-
Elastic cartilage is a specialized type of connective tissue found in certain areas of the body. It is characterized by its flexibility and suppleness, thanks to the presence of abundant elastic fibers within its extracellular matrix. This type of cartilage provides structural support and resilience to various organs and structures that require both strength and elasticity.
Elastic cartilage is primarily found in specific regions where flexibility is crucial, such as the external ear (pinna), the epiglottis (a flap of tissue in the throat), and the eustachian tube (which connects the middle ear to the back of the throat). The presence of elastic fibers enhances the cartilage's ability to withstand deformation and quickly return to its normal shape. This elastic property allows the cartilage to effectively absorb and distribute mechanical forces, protecting the surrounding tissues from damage or injury.
The extracellular matrix of elastic cartilage consists of cells called chondrocytes, embedded within a network of collagen, proteoglycans, and elastic fibers. These elastic fibers are primarily composed of the protein elastin, which enables the cartilage to stretch and recoil. Together with the proteoglycans, which provide hydration and support, the elastic fibers ensure the cartilage's structural integrity and flexibility.
Overall, elastic cartilage plays a vital role in maintaining the shape, support, and functionality of various body structures. Its unique composition and properties allow it to withstand repeated bending, stretching, and compression while efficiently returning to its original form.

Etymology of ELASTIC CARTILAGE
The word "elastic" comes from the Latin word "elāsticus", which in turn is derived from the Greek word "elastos". It signifies "flexible" or "resilient". "Cartilage", on the other hand, also originates from the Latin word "cartilago", which refers to "gristle" or "firmness". Combining these two terms, "elastic cartilage" describes a type of connective tissue that possesses both elasticity and firmness.
