Types of Bones

Question 1

What are the different type of bone cells

Answer 1

Osteogenic Cells/ Osteoprogenitor Cells
Osteoblast
Osteocytes
Osteoclasts

Question 2

Osteogenic Cells/ Osteoprogenitor Cells

Answer 2

bone stem cells - a cell that hasn’t been determined
after mitosis, one cell remains as osteoprogenitor while the other becomes a osteoblast

located:
endosteum
periosteum

Question 3

Osteoblast

Answer 3

secrete bone matrix until they are trapped in their lacuna and then become an osteocytes
- makes bones

Question 4

Osteocytes

Answer 4

mature bone cell within lacuna which detect mechanical stress (whenever there is pressure in the bone it communicates this to osteoblasts to form new bone matrix in order to resist the stress/pressure)

Question 5

• Osteoclasts

Answer 5

reserve bones; dissolving bones by utilizing hypocaloric acid

dissolves calcium and phosphate within the bone; release into the interstitual fluid eventually making it’s way to blood

phagocytosis cells that have HCL which dissolves calcium and phosphate of the bone matrix releasing it to interstitial fluid and then to the blood
- also contain lysosomes that dissolve organic portions of the matrix
