| Question |
Answer |
| Spongy bone found in |
epiphysis |
| Compact bone found in |
diaphysis |
| Occurs in epiphysis or red marrow |
hematopoiesis |
| Scientfic name for bone shaft |
diaphysis |
| site of fat storage |
yellow marrow cavity |
| region of longitudinal growth in a child |
epiphyseal plate |
| composed of hyaline cartilage until end of adolescence |
epiphyseal plate |
| layers of calcified matrix |
concentric lamellae |
| residence of osteocytes |
lacunae |
| canal that carries blood vessels and nerves |
central canal |
| nonliving structural part of bone |
bone matrix |
| tiny canals connecting lacunae |
canaliculi |
| bone forms from fibrous membrane |
intramembranous ossification |
| cartilage bones develop from |
hyaline cartilage |
| organic bone matrix |
osteoid |
| enzyme encourages deposit of calcium salts within matrix |
alkaline phosphate |
| when trapped in lacunae osteoblasts change into |
osteocytes |
| large number of osteoblasts found in |
inner periosteum layer |
| periosteal bud invades deteriorating hyaline cartilage shaft |
endochondral ossification |
| secondary ossification centers appear in |
epiphyses |
| epiphyseal plates made of |
hyaline cartilage |
| in appositional growth bone reabsorption occurs on the |
endosteal surface |
| maturation of newly formed bone matrix takes about |
10 days |
| hormone released when blood calcium levels begin to drop |
parathyroid hormone |
| mature bone cells maintain bone |
osteocytes |
| lack of muscle use causes muscle and bone |
atrophy |
| increased deposit of bony matrix occurs at sites of |
stress or tension |
| immature or matrix depositing bone cells are |
osteoblasts |
| causes blood calcium to be deposited in bones as |
calcium salts |
| bone cells that liquefy bone matrix and release calcium are |
osteoclasts |
