Facts About  Human Bones


~   Your skeleton is made up of 206 long, short, round, flat, big and little bones.


~    Half the bones in your body are in your hands and feet.


~   When you lift a glass of milk and take a sip, more than 30 joints move in your fingers, wrist, arm and shoulder.


~   Joints are where bones meet.


  ~  A baby may have as many as 350 bones, but as the child grows older, many of these grow together and form single bones, especially in the skull.

~   Throughout life, our bones are being remolded; old bone is broken down (resorption) and new born is formed (formation).


 ~    During childhood and teenage years, new bone is developed faster then old bone is removed. As a result, bones grow longer and denser.


~    Maximum bone density and strength is reached around age 30.


~   Maximum bone density and strength may never be reached if there is an inadequate amount of calcium in the body.


~   Calcium is not only needed for bone growth, calcium is also needed for other things such as nerve impulses, blood clotting, and muscle contraction.


~   Osteoporosis is a disease of the bones. If maximum bone density is not reached during the bone-building years, osteoporosis is more likely to develop later in life.


~   Osteoporosis can cause bones to become fragile, weak, and prone to fracture.


~    Environmental factors of osteoporosis are:

Getting enough calcium, exercising,  not smoking,  and avoiding excessive alcohol consumption. These factors can be controlled and can help lessen the risk osteoporosis.

~   Genetic factors such as being female, small-boned, and having a family history of osteoporosis, cannot be controlled.

 ~   The most effective way to build bone mass is weight bearing exercises. Weight bearing exercises are exercises that cause muscles to work against gravity. Examples are: walking, running, dancing, racquet sports, basketball, and soccer.
