When osteoclasts remove calcium salts faster than osteoblasts deposits them, it causes the bones to weaken.
that's when stimuli cause The cell injury and result is either cell adaptation ( Atrophy ) or in your case cell necrosis and finally bone recession . . .
Stress derived = Osteoclast Growth derived = Osteoblasts
A thickening of bone occurs called appositional growth after the growth plate closes in late teens. If this type did not occur and the bone would just get thicker, we would weight about 200 pounds more than we do. The bone inside is removed by osteoclasts (bone breakers) while bone on the outside is laid down by osteoblasts (bone builders).
Athletes consistently put force on their bones through activity. Force causes tiny electrical currents within the bone. These electrical currents stimulate the bone-forming activity of Osteoblasts. Since Osteoblasts produce bone tissue, this causes the bone to become denser and stronger.
Osteoclasts break down bone, which will essentially increase the amount of free calcium in the blood stream. Osteoblasts "build" bones from the free calcium in the blood. Calcium is involved in muscle contraction, so if you lack the necessary calcium in your diet, your body will actually break down bone material in order to obtain the necessary calcium for proper muscle function.
Active Transport!
Any of these changes may result if osteoblasts are more active than osteoclasts.
Stress derived = Osteoclast Growth derived = Osteoblasts
Bone is constantly remodeled during much of life by osteoblasts and osteoclasts. As such, the repair to a broken bone heals faster because it models the bone back in place, and sometimes it will heal stronger than it was before the injury.
chlorine is more active than bromine which is more active than iodine

Iron is several times more active than silver.
Fluorine is more active.
Boys are more active than girls.
Apex - trueYes, lithium is more active (reactive) than aluminum.
It's not as active as sodium, but it's more active than gold.
Cr, Fe, Co
Yes it is true. Your brain is more active sleeping than watching TV.
