==Structure and Function of Cartilage==

===Hyaline Cartilage===

===Hyaline Cartilage===

Hyaine cartilage is the most abundant in the body and surrounded by perichondrium. It is normally blue-white, smooth with a moist surface and turns yellow and becomes thinner in old age. It is found in nose, trachea, bronchi, ventral ends of ribs and sternal attachment. It provides a resilient, frictionless surface that resists compressionat at sites of articulation. It is also found at epiphyseal growth plates.

===Elastic Cartilage===

===Elastic Cartilage===

Elastic cartilage has a yellow appearance and is found in auricular cartilage, larynx, eustachian tube, and epiglottis. It is surrounded by perichondrium and has resiliance with added flexibility.

===Fibrocartilage===

===Fibrocartilage===

Fibrocartilage has more collagen ('''Type I''') and less proteoglycans than hyaline. It resists high tensional strain and is often in transition with hyaline. It is found in intervertebral discs, tendon/ligament attachment to bone, joint menisci, and articular surface of some joints (such as the temporomandibular). It has NO perichondrium.
