A
Metaphysis
3
Q
What is the physis?
A
Growth plate
4
Q
What is the bone on the joint side of the physis known as?
A
Epiphysis
5
Q
What are some differences between cortical and cancellous bone?
A
Cortical:
- diaphysis
- resists bending and torsion
- laid down circumferentially
- less biologically active
Cancellous:
- metaphysis
- resists/absorbs compression
- site of longitudinal growth (physis)
- very biologically active
