Adolescence and Puberty Quiz

Adolescence

• Adolescence is the period of life when the body changes, leading to reproductive maturity.
• It spans from around age 11 to 18 or 19.
• Also called the teenage years.
• Marked by puberty, which brings significant physical, emotional, and mental changes.

Puberty

• Puberty is when the body and reproductive organs change, leading to sexual maturity.
• Key change: boys and girls become able to reproduce.
• Girls usually enter puberty a year or two earlier than boys.
• Changes vary, and include height, body shape, voice, sex organ development, and more mental, emotional maturity.
• Secondary sexual characteristics develop as visible differences between sexes.

Changes During Puberty

• Boys: facial hair, body hair (underarm, abdomen, chest, pubic), wider chest/shoulders, muscular build, rougher skin, increased sweat and oil production, deeper voice.
• Girls: breast enlargement, body hair (underarm, pubic), wider hips, increased fat in certain areas (hips, buttocks, thighs), development of secondary reproductive organs.

Mental and Physical Changes During Puberty: Reproductive Health

• Reproductive health involves the well-being of reproductive organs, a crucial aspect of overall health during adolescence.
• Organs develop and become functional.

Endocrine Glands

• Endocrine glands are ductless glands that produce hormones, chemical messengers regulating body functions and systems.
• Hormones are released directly into the bloodstream.

Hormones

• Hormones control bodily functions, physiology, and behaviors.

Pituitary Gland

• The pituitary gland, a "master endocrine gland" in the brain, controls other glands via hormones.
• It produces growth hormone which is highest during adolescence.

Testosterone

• The primary male sex hormone, triggering male reproductive organ development, sperm production, and secondary sexual characteristics.
• Testes start producing it during puberty.

Oestrogen

• The primary female sex hormone, developing female reproductive organs, ova production, secondary sexual characteristics and menstrual cycle.
• Ovaries begin producing it after puberty.

Thyroid Gland

• Butterfly-shaped gland in the throat, secreting thyroxin.
• Crucial for metabolic balance; deficiency can lead to goiter(thyroid gland swelling).

Pancreas

• Secretes insulin, regulating blood sugar.
• Insulin deficiency causes diabetes.

Adrenal Glands

• Located above the kidneys, changing shape throughout life.
• Secrete adrenaline ("fight or flight" hormone) and regulate salt & pH balance.

Menstrual Cycle

• A female reproductive cycle marked by the release of an egg and cyclic changes in the ovaries and uterus.
• Begins at puberty (menarche).
• If fertilized, pregnancy occurs; if not, the uterine lining sheds (menstruation).
• Women reach menopause between ages 45-52.

Sex Determination

• Humans have 23 chromosome pairs, with one pair determining sex (X and Y).
• Females have XX; males have XY.
• Female gametes (ova) have an X chromosome.
• Male gametes (sperm) have either an X or Y chromosome.
• The sex of the child is determined by the sperm's chromosome.

Personal Hygiene

• Maintaining personal hygiene is critical during adolescence due to increased sweat and oil production.
• Daily washing is crucial for infection prevention.

Balanced Diet

• A balanced diet is essential for adolescent growth and development.
• It includes proteins, carbohydrates, fats, and vitamins.
• Avoiding junk food is recommended for healthy growth.

Physical Exercise

• Regular exercise promotes both physical and mental well-being.

Drugs

• Drugs are harmful and addictive.
• They cause long-term, possibly irreversible damage.
• Teens should avoid drugs.
