MACRO + MICRO STRUCTURE OF BONE
LO's:
Wolff's Law
Trabeculi where there is need for force resistance
Lamellar bone
Layed down in packets
Mechanical terms
Strength
Maximum stress a material can bear without failing
Measured in GPa
Toughness
Energy required before material fails
Measured in joules per unit volume
Stiffness
Amount a structure deforms when force is applied
Measured in newtons per feature
Properties
Elastic modulus
Describes how much a material deforms elastically under a given stress
Measure in GPa
INTENSIVE
Relating to materials
EXTENSIVE
Relating to structure
Cross-sectional area
Bone allometry
Change in proportion with size
Effects:
Whole bones
Trabecules
With size
Thickness + spacing increase
