osteoblasts
osteoclasts
when too much calcium is depleted from bone, ________ results.

osteoporosis
_________ secretion allows mineralization in bones.
osteoblasts
_______ protein gives bone flexibility, minerals that encrust those fibers give them strength.

___________ disease results from the genetically-bases corruption of bones collagen matrix.
brittle bone disease
collagen matrix is organized into long concentric layers, called ________. (growth rings)
lamellae

lacunae
canaliculi
grouping of concentric lamellae is called an ________.
osteon
the _________ are passageways for nerves and blood, the _________ connect perpendicular and oblique
central (Haversian) canals
perforating (Volkmanns) canals
