Osteoprogenitor Cells
Stem cells from mesenchyme, found in endosteum and periosteum, produce either another stem cell or an osteoblast
Osteoblast
Forms bone matrix, “builds bone,” differentiates into osteocytes
Osteocytes
Maintain the bone matrix and communicate with osteoblasts which deposit further bone matrix
Osteoclasts
Large, multinuclear cells that dissolve bone.
What and what have opposite effects on bone density and serum calcium?
Osteoclasts and osteoblasts
Epiphysis
An expanded, knobby region at the end of a long bone
Diaphysis
Shaft of a long bone
Metaphysis
