bone tissues + functions

Question 1

osteoblasts function + where they are found

Answer 1

-form new bone by depositing calcium phosphate crystals (bone matrix)
-inner most layer of periosteum

Question 2

osteoclasts

Answer 2

-breakdown bone during remodeling, or when calcium is needed in the blood
-inner most layer of periosteum

Question 3

osteocyte

Answer 3

-mature bone cells that are embedded in bony matrix after ossification. Serve as a maintenance
-lacunae

Question 4

central canal function

Answer 4

blood vessels and nerves found here
it is parallel to the long axis of the bone

Question 5

lacunae function

Answer 5

small cavities that house osteocytes suspended in tissue fluid

Question 6

osteon function (made layer of lamallae)

Answer 6

concentric rings of lamella

Question 7

canaliculi function

Answer 7

small channels that extend from lacunae to the central canal
passageways though solid matrix for cells to pass and connect living cells of the osteon to the nutrient supply

Question 8

periosteum

Answer 8

thin layer of connective tissue
takes care of the bone + tendon
