Question 28

Bone remodeling( only chondoblasts, chondrocytes)

Answer 28

Involves bone
resorption (removal of
mineral and collagen
fibers) by Osteoclasts
and new bone
deposition (addition

Question 29

Hormonal regulation of bone growth

Answer 29

1 GH: : produced by the pituitary gland
Stimulates epiphyseal plates
• Thyroid & parathyroid hormones – ensures that the skeleton retains
proper proportions
• Sex hormones
Promote bone growth
Later induces closure of epiphyseal plates
