Cellular structure[edit | edit source]

Molecular structure[edit | edit source]

Matrix[edit | edit source]

  • Inorganic
  • Organic

Woven or lamellar[edit | edit source]

Types[edit | edit source]

Formation[edit | edit source]

Intramembranous ossification[edit | edit source]

Endochondral ossification[edit | edit source]

Bone marrow[edit | edit source]

Remodeling[edit | edit source]

Purpose[edit | edit source]

Calcium homeostasis/balance must exist between osteoclasts and osteoblasts activity[edit | edit source]

  • If too much new tissue is formed, the bones become abnormally large and thick (acromegaly)
  • Excessive loss of calcium weakens the bones, as occurs in osteoporosis

Repair[edit | edit source]

Paracrine cell signalling[edit | edit source]

Osteoblast stimulation[edit | edit source]

Osteoclast inhibition[edit | edit source]

Disorders[edit | edit source]
