- Avascular (poor healing) - ECM is solid with lucunae (holes) and good at resisting compression and is somewhat pliable - GAG's are basophilic (negatively charged) so it stains blue or purple - will salso stain well with PAS (because its high in carbohydrates)
- gives pliable support to softer tissues - shock absorber - smooth low friction surface - template for endochondral bone growth
can we see the fibers? (if so how are they arranged)
- no visible fibers in the ECM
type of collagen? how its arranged?
what does the ground substance consist of? (making it what)
