Facts About to know about 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.
