2. concentric layer
3. interstitial layer

Question 2

describe the circumferential layer

Answer 2

surrounding the outer most perimeter of the adult bones

Question 3

describe the concentric layer (circles)

Answer 3

make up the BULK of the compact bone and metabolic unit of bone called “osteon”

Question 4

describe the interstitial layer

Answer 4

b/w the concentric circles

Question 5

when we have our osteoblasts make bone

Answer 5

…then they are called osteocytes
…they make them in these concentric circles
…will have laminae
…which are organized into these concentric rings
…then these concentric rings then will have a canal called haverson canal
…each canal will have the laminae and osteocytes
