1. Cartilage

2. 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

3. 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

4. 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

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