What are the two types of supportive tissue? |
* Cartilage * Bone |
|
Describe Cartilage (4). |
* Rigid matrix * Tough and flexible * No innervation * Surrounded by fibrous CT |
|
What does the prefix Chond mean? |
Cartilage |
|
What is Perichondrium (3)? |
* Low metabolism * Slow healing chondrocytes in lacunae within a matrix of polysaccharide gel-like ground substance (with a lot of water) * Poor blood supply |
|
What are the three types of Cartilage? |
* Hyaline * Elastic * Fibrocartilage |
|
Describe Hyaline cartilage (3). |
* Most common, amorphous matrix * With very fine collagenous fibers (too fine to see with our microscopes) * Makes up: the ends of bones, nose, respiratory passages and the embryonic skeleton |
|
Describe Elastic cartilage (2). |
* Flexible (due to elastic fibers) * Makes up external ear, larynx, epiglottis |
|
Describe Fibrocartilage (5). |
* Very tough (due to many collagenous fibers) * Tensile strength * Shock absorber * Intervertebral discs * Pads of knee & pelvic girdle, pubic symphysis & meniscus |
|
What are the Components, Cells, Fibers, ECM & Features of Cartilage? |
* Hyaline, Elastic & Fibrocartilage * Cells: Chondroblasts & Chondrocytes * Matrix: Gel-like ground substance * FIbers: collagen & elastic * Features: Resists compression because it holds so much water in its matrix; Cushions and supports body structures |
