contains 126 bones of extremities
appendicular skeleton
bone is made up 1/3
organic
bone is made up 2/3
inorganic
type of bone, hard , dense outer shell
compact bone
-porous and spongy portion
-make up most of the articular ends of bones
cancellous bone
area at end of each diaphysis
epiphysis
longitudinal bone growth occurs here through manufacturing of new bone
epiphyseal plate
main shaft of bone ( made up mainly of compact bone )
diaphysis
center of diaphysis, hollow
medullary canal
membrane that lines the medullary canal, contains osteoclasts
endosteum
mainly responsible for for bone resorption
osteoclasts
made up mostly of cancellous bone and supports the epiphysis, this is in long bones and is flared at the end of diaphysis
metaphysis
thin fibrous membrane covering all the bone except the articular surfaces
periosteum
covered with hyaline cartilage
articular surfaces
two types of epiphyses found in children
pressure and traction
found in children, located at the end of long bones where they receive pressure from the opposing bone making up the joint (where long bone growth occurs)

crest
prominence above or on a condyle
epicondyle
less prominent ridge
line
long thin projection
spine
small, rounded projection
tubercle
large, rounded projection
tuberosity
