Answer 1

In Girls

1. Puberty in girls is marked by the start of the menstruation cycle, commonly referred to as periods.
2. A major physical development is that of the breast that grows during the teenage years and attains full growth by the age of 18 years.
3. Hair growth in the pubic area and the armpits are also observed. The normal cycle of hair growth that is seen in adults is reached by the average age of 14 years.
4. The adolescent years are also marked by a rapid growth spurt. In girls this growth spurt starts at the age of 11 or usually around the time she reaches menarche and slows down by the age of 16.

In boys

1. In boys, the scrotum and the testicles start to grow when they reach puberty.
2. The penis also increase in length and reaches the proper adult size and shape by the age of 17 or 18.
3. There is a hair growth observed in the pubis area, armpits as well as the chest and the face. This usually starts around the age of 12; by the time the boy reaches 18 years of age, the pattern of hair growth resembles those of adults.
4. The growth spurt starts at about 13 years and continues on to about 18 years of age. After that, the growth slows down.
5. Another physical change that is observed in adolescent boys is the change in their voices. Their vocal cords grow and as a result, the voice pitch changes into a heavier tone.
6. Physical development and changes at such a sudden and fast rate is quite something for the adolescent kid to deal with. This is the time when the child is in constant need of support and care.

Reason

Puberty is the body's natural process of sexual maturation. Puberty's trigger lies in a small part of the brain called the hypothalamus, a gland that secretes gonadotropin-releasing hormone (GnRH). GnRH stimulates the pituitary gland, a pea-sized organ connected to the bottom of the hypothalamus, to emit two hormones: luteinizing (pronounced LOO-tee-uh-nize-ing) hormone (LH) and follicle-stimulating hormone (FSH). These two hormones signal the female and male sex organs (ovaries and testes, respectively) to begin releasing the appropriate sex hormones, including estrogens and testosterone, which launch the other signs of puberty in the body.¹
