Question 2

What are the organic and inorganic components of cortical bone

Answer 2

Organic = T1 Collagen
Inorganic = Hydroxyapatite

Question 3

What is the Haversian Canal

Answer 3

Supplies single osteon and allows communication between osteons w/ Volkmann canals

Question 4

Whats the difference between Haversian and Volkmann canal

Answer 4

Haversian = Supplies single osteon
Volkmann = Allows communication between osteons
