Basic Bone Biology

• Bone has both a mineral and an organic component• Organic: 90% is collagen (a type of protein)• Mineral: hydroxyapatite (calcium phosphate)

• Has multiple functions:• Mechanical• Nutrient storage• Cell formation

• Is responsive to its environment

Wolff’s Law = Form Follows Function25

In your bag… • How do the bones fit together?• Can you identify:• an epiphisis• a diaphysis• cortical bone• trabecular bone

• Is there a joint? If so, what kind? What movements are possible?• Using “Bucky” as a guide, can you determine what

bones you have?
