Adolescence

The period of life when the body undergoes several changes to reach sexual maturity is called Adolescence, or Growing up stage of life.

The stage of adolescence usually begins at ages 13 – 14 for boys, and ages 10 – 12 for girls.

However, this may vary from person to person.

The occurrence of adolescent changes in the body marks the onset of puberty.

The stage of puberty ends with the attainment of sexual maturity in an adolescent.

The changes which take place in the body of an adolescent are:

(I) Change in Body shape

These changes are different for boys and girls. While in boys, the shoulders become broad and the chest becomes wide, in girls, the region below the waist becomes wider. Also, muscular development is more prominent in boys than in girls.

(II) Change in voice

This occurs because at the time of puberty in boys, the voice box or the larynx begins to grow and protrude from the throat. This is called an Adam’s apple. The enlargement of the larynx makes the voice low pitched and hoarse. In girls, the voice becomes high pitched.
