Bone Flashcards
1
Q
Functions of bone?
A
-strong and dynamic support
-constantly metabolically active
-vascular with nervous system
2
Q
Spongy Bone
A
-surrounds medullary cavity (which contains bone marrow)
-minimizes weight
trabeculae form along lines of stress for extra strength
3
Q
Compact Bone
A
-dense outer shell
-deep to the periosteum (which is connected to deep fascia)
-resists compressive forces, strength with bending
4
Q
Bone Matrix
A
-bone minerals (crystals with calcium carbonate)=brittle strength
-collagen =flexible, twisting, bending
