New cards

axial - 80 bones

appendicular - 126 bones

2 major division of skeletal system

2
New cards

longer than they are wide, consists of a shaft w head at either end

3
New cards

compact bone

long bones are primarly…

4
New cards

more spongy bone than compact

short bones are what type of bone

5
New cards

flat bones

flattened among major aspect of their geometry but can be curved, two wafer like layers of compact bone between layer of spongy

6
New cards

cortex

the collective compact bone later of flat bones

7

diploe are filled with…

10
New cards

periosteum

fibrous layer that covers the compact bone surface

11
New cards

outer fibrous layer

13
New cards

diaphysis

long central shaft of long bone

14
New cards

proximal epiphysis

end of long bone closest to trunk of body

15
New cards

distal epiphysis

end of long bone further away from trunk

16
New cards
