Question 2

Osteoblasts

Answer 2

builds ECM-responsible for synthesizing cell responsible for bone growth

Question 3

Osteocyte

Answer 3

mature bone cell that monitors and maintains the mineralized bone matrix

Question 4

Osteoclasts

Answer 4

breaks down ECM “bone-resorbing cell”

Question 5

Compact bone gross level

Answer 5

outer surfaces seem impenetrable.

foramina/holes

Question 6

Osteon CB

Answer 6

longitudinal unit within comapct bone.

function=maintaining osteocytes by providing nutrients

Question 7

Lamellae

Answer 7

tubes of ECM with collagen fibers aligned to resist forces “extra bone tissue”.
form a series of cylinders running down shaft=forming osteon

Question 8

Central canal

Answer 8

contains blood vessel and nerves

Question 9

lacunae

Answer 9

lakes for osteocytes

Question 10

canaliculi

Answer 10

channels for osteocytes through ECM

Question 11

compact bone tissue do what

Answer 11

keep compact bone vital

Question 12

cancellous bone trabeculae

Answer 12

struts of lamella bone.
marrow fills the cavities.
osteocytes housed in lacuna on surfaces of trabeculae
