Definitions: Journal Post 5

Cartilage was a focus last week and I wanted to take this time to refresh myself on the different cartilage types and how to tell them apart.




Hyaline Cartilage- This type of cartilage is present in places with support and flexibility are needed. It is typically found in joints and the respiratory tract. The cartilage itself is typically uniform and shiny in appearance with chondroctyes that are evenly dispersed.









Elastic Cartilage- The fibers in this cartilage type are easily visible, which include elastic fibers. A perichondrium is also present. Elastic cartilage can be found in places where elasticity is needed including the epiglottis and ear lobes.




Fibrocartilage- Fibrocartilage is characterized by the collagen fibers that appear to be layered upon one another. Fibrocartilage appears more open then the other two cartilage, making it a very good shock absorber. It is present in places where stress is added to the body in order to prevent severe damage. These places include the knees and feet.
