Study Notes
Reaching the Age of Adolescence
- Adolescence is a period of life between childhood and adulthood, marked by physical and hormonal changes.
- Puberty is a period when the body undergoes changes leading to reproductive maturity.
- Puberty generally begins between the ages of 10 and 18 or 19.
- Growth spurt occurs during puberty and is noticeable in height.
- Adolescents experience changes in body shape, voice, and development of secondary sexual characteristics.
- Hormones (like testosterone and estrogen) regulate these changes.
- The pituitary gland controls the release of hormones that stimulate the testes and ovaries.
- The testes produce testosterone, and the ovaries produce estrogen.
- Secondary sexual characteristics in males include facial hair, broader shoulders, and deeper voices.
- Secondary sexual characteristics in females include breast development.
- Adolescents should have a balanced diet for proper nutrition and growth.
- Hygiene and exercise are important for maintaining overall health and well-being.
- Increased activity of sweat and sebaceous glands leads to acne during adolescence.
- The human body undergoes various changes during adolescence.
- Height increases, secondary sexual characteristics and other changes take place.
- The changes in adolescent period are natural and essential parts of growing up.
Puberty
- Puberty is a period of life during which the body undergoes changes leading to reproductive maturity in both boys and girls.
- Adolescence is the period associated with puberty.
- Puberty generally starts between the age of 10-12 years.
- Body shape, facial hair and voice changes are noticeable in this period.
- This period includes rapid growth spurts and increase in height.
- During puberty, the body gets prepared to reproduce.
Changes at Puberty
- Height increase is a prominent change during puberty.
- Bones of arms and legs grow rapidly during growth spurt.
- Girls start growing taller than boys initially but the growth rate is slow down by about the age of 18 or 19 years.
- Boys also go through a growth spurt and reach their maximum height by the ages of 18-20.
Secondary Sexual Characteristics
- Secondary sexual characteristics are the physical features that distinguish one sex from another.
- These include body hair (underarms and pubic areas), changes to the voice (deeper and more prominent in males), increases in the width of shoulders (in males), and the development of breasts (in females).
Hormones
- Hormones are chemical substances that regulate changes in the body.
- Hormones are produced by endocrine glands.
- Specific hormones control puberty and reproductive functions (eg., testosterone, estrogen).
- Endocrine glands release hormones directly into the bloodstream.
- The hormones regulate the onset of puberty.
Nutritional Needs of Adolescents
- Adolescence is a period of rapid growth and development.
- An adequate diet is required during this period since adolescents need a greater quantity of nutrients for this development.
