Question 1

Blood cell formation is called .

Accepted Answer

hematopoiesis

Question 2

Bones appear to be lifeless structures.Does bone material renew itself?

Accepted Answer

Bone only appears lifeless in gross anatomy.Microscopically,bone is full of cells and blood vessels that maintain and renew bone tissue.Approximately 5% to 7% of our bone mass is recycled each week.Up to 0.5 g of calcium may enter or leave the bones each day,depending on the negative feedback hormonal mechanism and gravitational forces.

Question 3

How can a tooth be moved in a bony socket during orthodontic treatment?

Accepted Answer

Because bone deposition and reabsorption can occur,and because bone responds to mechanical stress Wolff's law),a tooth can be moved.By applying slight pressure to a tooth,the bone on the forward side will reabsorb,while the bone on the reverse side will be reformed.
