1. Adolescence is generally defined as the developmental period between:
A) Birth and age 5
B) Ages 5 and 10
C) Puberty and adulthood
D) Age 18 and 25
Correct Answer: C) Puberty and adulthood
Rationale: Adolescence is the transitional period between puberty and adulthood, typically beginning
around ages 10–12 and extending through the late teens or early twenties. Options A and B describe
childhood periods, and D describes emerging adulthood.
2. The hormonal cascade that initiates puberty begins when the hypothalamus releases:
A) Luteinizing hormone (LH)
B) Follicle-stimulating hormone (FSH)
C) Gonadotropin-releasing hormone (GnRH)
D) Estrogen and testosterone
Correct Answer: C) Gonadotropin-releasing hormone (GnRH)
Rationale: The hypothalamus releases GnRH, which signals the pituitary gland to release
gonadotropins (FSH and LH). These gonadotropins then trigger the production of sex hormones in the
gonads. Options A and B are released by the pituitary, and D are the final sex hormones.
3. The pituitary gland, in response to GnRH, releases which hormones?
A) Estrogen and progesterone
B) Testosterone and androgen
C) Follicle-stimulating hormone (FSH) and luteinizing hormone (LH)
D) Adrenalin and cortisol
Correct Answer: C) Follicle-stimulating hormone (FSH) and luteinizing hormone (LH)
,Rationale: The pituitary gland releases FSH and LH (gonadotropins) in response to GnRH from the
hypothalamus. These hormones then stimulate the gonads to produce sex hormones. Options A and B
are sex hormones produced by the gonads, and D are stress hormones.
4. Which sex hormones does LH trigger the production of?
A) Estrogens and androgens
B) Adrenalin and cortisone
C) Insulin and oxytocin
D) Vasopressin and thyroxine
Correct Answer: A) Estrogens and androgens
Rationale: LH stimulates the gonads (ovaries in females, testes in males) to produce estrogens and
androgens, the primary sex hormones. Options B, C, and D are not sex hormones triggered by LH.
5. The "domino effect" in puberty refers to the sequence:
A) Gonads → pituitary → hypothalamus
B) Hypothalamus → pituitary → gonads
C) Pituitary → hypothalamus → gonads
D) Gonads → hypothalamus → pituitary
Correct Answer: B) Hypothalamus → pituitary → gonads
Rationale: The domino effect describes the sequential activation: the hypothalamus releases GnRH,
which triggers the pituitary to release gonadotropins, which then stimulate the gonads to produce sex
hormones. Options A, C, and D present incorrect sequences.
6. The average age for the onset of puberty in girls is approximately:
A) 8
B) 10
C) 12.5
D) 14
Correct Answer: B) 10
, Rationale: The average age for the onset of puberty in girls is approximately 10 years old. Option A (8)
is the lower end of the normal range, C (12.5) is the average age of menarche, and D (14) is later than
average.
7. The average age for the onset of puberty in boys is approximately:
A) 10
B) 11.5
C) 12.5
D) 14
Correct Answer: C) 12.5
Rationale: The average age for the onset of puberty in boys is approximately 12.5 years old. Option A
is the average for girls, B is slightly early for boys, and D is later than average.
8. The average age of menarche (first menstruation) for girls in North America is approximately:
A) 10
B) 11
C) 12.5
D) 14
Correct Answer: C) 12.5
Rationale: The average age of menarche in North America is approximately 12.5 years. Option A is the
average age of puberty onset in girls, B is slightly early, and D is later than average.
9. The average age that girls in North America finish growing is approximately:
A) 14
B) 16
C) 18
D) 20
Correct Answer: B) 16
Rationale: Girls in North America typically finish growing by approximately age 16. Option A is too
early, C is the average for boys, and D is later than typical.
