What happens when bones do not get enough calcium?

The units that make up compact bone are called
periosteum
central canals

How does estrogen affect bone growth?
Estrogen causes bones to soften and deform.
Estrogen stimulates osteoclast activity which destroys bone.
Estrogen stimulates ossification of the growth plate.
Estrogen helps us absorb calcium from our food.
