osteoblasts correct answers build new bone
osteoclasts correct answers dissolve bone
osteocytes correct answers trapped osteoblasts surrounded by hardened osteoid
where do osteoblasts originate? correct answers mesenchymal stem cells
where are osteoblasts active? correct answers outer surface of bones
main hormone that affects osteoblasts correct answers parathyroid hormone
when active, osteoblasts secrete: correct answers osteoid
when resting, osteoblasts are termed: correct answers satellite cells
most abundant bone cells correct answers osteocytes
osteoid correct answers unmineralized bone matrix
lacuna correct answers small cavities in bone that contain osteocytes
Osteocytes act as _________ to adjust bone shape and density to adapt to stress correct
answers mechanoreceptors
