Introduction Bone is the dense, calcified connective

tissue it form the major portion of the skeleton.

Functions of the bone: Protection. Support. Movement.

What is osteoporosis? It’s an acquired condition characterized by

reduces bone mass, leading to bone fragility and susceptibility to fracture.

Osteoporosis-related fractures most commonly occur in the hip, wrist or spine.

Explain why women run a higher risk for bone fracture after menopause?

Menopause

Ovaries decreased production of the

reproductive hormone estrogen

Lack of estrogen Enhance ability of osteoclasts to

absorb bone

Osteoblasts aren't similarly nourished to rebuild the bone

More bone is lost and women can develop osteoporosis

which increases the risk of sudden and unexpected

fractures.

Summary Osteoporosis is a condition

characterized by reduces bone mass.

Menopause is one of the strongest risk factors for developing osteoporosis.
