Tissues
|
- Groups of similar cells
- surrounding substances working together to perform a common function |
|
|
Cartilage
|
- type of CT
- NOT bone tissue - capable of enduring considerable stress - NO nerves - NOblood vessels |
|
|
Cartilage
|
- Extracellular matrix includes
* mostly water ~ 75% * collagen ~ 15%- strength * elastic fibers embedded in chondroitin sulfate~resilience- ability to return to original shape after deformation |

Cartilage
|
Cells
- chondroblasts - make cartilage matrix - chondrocytes - mature cell; maintains matrix - both housed within a lacuna |
|
|
Cartilage
3 types |
Hyaline
Fibrocartilage Elastic Cartilage |
|
|
Hyaline
|
- fine collagen fibers
- end of long bones & anterior ends of ribs - nose of embryo/fetus - parts of larynx, trachea, bronchi, bronchial tubes - provides smooth surface for movement - gives support, flexibility w/ resilience |
|
|
Fibrocartilage
|
- collagen fibers are recognizable
- interpubic disc - intervertebral discs/ IVDs - menisci (pads of fibrocartilage) - strong support - resists stretching |
|
|
Elastic Cartilage
|
- Chondrocytes in threadlike network of elastic fibers
- E3 Epiglottis External Ear Eustachian tube - supports & maintains shape - exceptional stretchability |
