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
