another name for mature bone cells | osteocytes |
osteocytes come from | osteoblasts |
function of osteocytes | directs the release of Ca from bone to bone And deposition of CaNa’s in bone matrix |
Location of osteocytes | lacunae (small chamebers) btwn the calcified matrixLacunae are connected by canaliculi (sm canals) through outhe bone matrix |
another word for lacunea | small chambers, houses the osteocytes |
another word for canaliuli | canals or vessels connecting the lacunea |
four types of cells found in bone | osteocytes, osteoblasts, osteoprogenitor, osteoclasts |
cubidal in shape secretes osteoid- stuff that is mineralized and becomes the bone matrix | Osteoblasts |
