Bones support‚ move‚ and protect the body; they also give us our features. But without bone cells we would have no bones.

They also carry out other small roles. There are four main types of bone cells: Osteogenic‚ which are bone cells that respond to traumas‚ osteoblasts‚ which form bone matrix around themselves

Osteoblasts are the specific types of cells that produce the normal microanatomy of the tissue. 5a. With ageing‚ bone mass decreases. This is espeically true of women following menopuase. Estrogen acts as a protector of bone by inhibiting the activity of osteoclasts. Once estrogen levels drop‚ after menopause‚ osteoclast activity increases. 5b. Bone mineral density (BMD)
