Cartilage

components Chondrocytes – mature cells Collagen fibers – protein fibers responsible for strength Elastic fibers Chondroitin sulfate – provides elasticity Membrane covers surface No blood vessels or nerves http://education.vetmed.vt.edu/curriculum/vm8054/labs/Lab7/lab7.htm

Hyaline cartilage Most abundant type Lots of chondrocytes Ends of bones, nose, trachae, larync, bronchi Provides smooth surface for movement, shock absorption, flexibility & support Weakest of the types http://seymourchiropractic.ca/images/glucopic.jpg

fibrocartilage Chondrocytes scattered Bundles of collagen Intervertebral discs, pubic symphysis, menisci (knee), parts of tendons that insert into cartilage Provide support and fusion Strongest of the 3 also rigid http://www.ssmedgroup.com/medpics/meniscaltear.jpg

Elastic Cartilage Chondrocytes in a threadlike elastic fiber network Epiglottis, external ear Provides support and maintains shapes
