Bone Flashcards
structure of a long bone
epiphysis
epiphyseal plate
diaphysis
epiphysis
the area at each end of the bone
osseous in adults
action vs pressure epiphysis
epiphyseal plate
a cartilaginous area where growth occurs in long bones
replace by bone once growth has end
diaphysis
the main shaft of bone
the center is the medullary canal
(provides nutrition)
structure of bone
metaphysics
endosperm
periosteum
traction epiphyses
create bone growth and creates tension at the origin/insertion of muscles (non weight bearing)
pressure epiphyses
compression that creates bone growth at the end of the bone (weight bearing)
bone architecture
organic and organic material
organic materials in the bone
blood, collagen, proteoglycan
inorganic materials in the bone
calcium, hydroxyapatite crystals
Cortical/compact bone
protection
hard outer shell
cancellous bone (spongy/trabecular bone)
porous and spongy inside called the trabeculae
woven bone
- immature bone
- bone tissue that has not completely mineralized such as in adolescence or during callus formation
Osteon = Haversian system
- functional unit of compact bone
- made up of lamellae with cells between osteocyte connected to each other via dendrites traveling through canaliculae
periosteum
