Microscopic bone anatomy Flashcards
1
Q
Osteogenic cell
A
- Literally ¨bone produce¨
- Are stem cells
- Only type of bone cell that does mitosis
- Divide to form osteoblasts
- Located in the periosteum and endosteum
2
Q
Osteoblast
A
- Literally ¨bone bud/sprout¨
- Build new Bone
- Make bone’s matrix called osteoid (calcium + collagen + water)
- Get trapped & become osteocytes
- Located on the periosteum and epiphyseal plates
3
Q
Osteocyte
A
- Literally ¨bone cell¨
- Mature bone cells
- Located in compact bone and spongy bone
- Perform daily functions of bone
4
Q
Osteoclast
A
- Literally ¨bone break¨
- CLean/CLear away bone
- Located on the periosteum and endosteum
- Used during fracture repair and bone growth (clean away old bone from the medullary cavity)
5
Q
The primary mineral stored by compact bone is
A
Calcium
6
Q
What type of bone makes up the diaphysis?
A
Compact bone
7
Q
Diaphysis
A
Shaft of a long bone (middle)
8
Q
Epiphysis
A
Ends of a long bone where joints are found
9
Q
Periosteum
A
Outside covering of the diaphysis
10
Q
Sharpey’s Fibers
A
Holds periosteum to the underlying bone
11
Q
Arteries
A
Supplies bone cells with nutrients
12
Q
Articular cartilage
A
Decreases friction at joint surfaces
