Question 4

Which part of a long bone contains the central cavity filled with yellow bone marrow?

Accepted Answer

Diaphysis

Question 5

What is the primary function of canaliculi in compact bone?

Question 7

Which of the following best describes the arrangement of osteocytes in compact bone?

Accepted Answer

Arranged in concentric rings around a central canal

Question 8

If the Haversian canal in an osteon is blocked, what is the most likely consequence?
