Discuss about the structural changes in the human body that occurs during the onset of puberty.
A. Structural changes in male
The boys begin their adolescent growth spurt at an average of about 10 years and attains maximum at the age of 18. B. Voice change
Under the influence of androgens, the voice box, or larynx, grows in both genders. This growth is far more prominent in boys, causing the male voice to drop and deepen. Full adult pitch is attained at an average age of about 15 years. When the larynx grows larger during puberty, it sticks out at the front of the throat. This is what's called an Adam's apple.C. Body and facial hair:
The appearance of hair in the areas of skin responds to action of androgens. There is a large range in amount of body hair among adult men, and significant differences in timing and quantity of hair growth among different ethnic groups.D.Male musculature and body shape:
By the end of puberty, adult men have heavier bones and nearly twice as much skeletal muscle. Some of the bone growth (e.g., shoulder width and jaw) is disproportionately greater, resulting in noticeably different male and female skeletal shapes.E.Structural changes Female:Changes in height
The girl begins her adolescent growth spurt at an average of about 10 years and grows at peak velocity at about 12 years, attains her adult height at about 16 years.Underarm (axillary) hair growth visibleBody odor and Pimples
Rising levels of androgens can change the fatty acid composition of perspiration, resulting in a more "adult" body odor. As in girls, another androgen effect is increased secretion of oil (sebum) from the skin and the resultant variable amounts of acne and pimples. This can be prevented or diminished by antibacterial face washes and by reducing the intake of high fat content in food. It is fully diminished at the end of puberty. Over sweat secreted by the sweat glands is also one among the change.Body shape, fat distribution, and body composition
During this period, also in response to rising levels of estrogen, the lower half of the pelvis enlarges in size and thus hips widen (providing a larger birth canal).
