Answer 1

The average boy has his fastest rate of growth in height between ages 13 and 14, and stops growing between ages 17 and 18. Peak bone mass occurs 9 to 12 months after the peak rate in height growth. Early or late onset of puberty affects peak bone mass.

Answer 2

We are composed of one skeleton that can be divided into two major regions, the axial and appendicular skeleton. The axial skeleton makes up our central axis and consists of the following bones: skull, vertebrae, ribs and sternum. The appendicular skeleton consists of the limbs and girdles.
