Ch. 7 Bone Structure and Function
Cells
Osteoprogenitor
Stem cells
Osteoblasts
Secret bone matrix
Osteocytes
Maintain bone matrix
Osteoclasts
Resorption
Hematopoietic stem cells
Bone Matrix
Organic
Tensile strength
Calcium phosphate salts
Inorganic
Compressional strength
Collagen
Reservoir for minerals (bone tissue)
Vitamin D increases absorption of calcium
Interstitial Growth
Epiphyseal plate narrows until it disappears
Remnant epiphyseal line
Growth in length due to growth in hyaline cartilage
Later replaced with bone
Bone remodeling
Deposition
Addition of new bone tissue
Resorption
Removal of old bone tissue
Mechanical stress
Stress detected by osteocytes, communicated to osteoblasts
Osteoblasts increase synthesis of osteoid, deposition of mineral salts
Ossification (osteogenesis)
Intramembranous
Mesenchyme
Endochondral
Cartilage
