1) Articular - Lines joins and provides bearing surface.
2) Elastic - Ribs
3) Fibro - Provides shape and stiffness (ears)
Explain how articular cartilage works.
The cartilage is filed with MPS which have negative points where water can weakly bind. This makes a hydrogel (Synovial fluid) which behaves elastically under fast loading and flows under slow loading (Thixotrophy).
What two materials are bone made out of?
1) Collagen for tensile loading with
2) discrete nano-sized Hydroxapetite for compression and crack propagation prevention.
