1. What is the age of adolescence?: onset is puberty and then the end is
when an adult role is assumed (harder to define)
2. What is the average age in North America for the start of pubertal
growth spurt?: 10 years old for girls
12.5 years old for boys
3. What is spermarche? When does it occur?: onset of sperm emission is
age 13 in North America
4. What is menarche? When does it occur?: first menstrual period is age
12.5 in North America
5. What is the secular trend for menarche?: decrease in average age of girls
experiencing their first period which has affected most members of society
6. Explain why the average age for menarche has dropped and plateaued
since the 1800s/1900s.: Due to modernized countries and more access to food
Improved nutrition increases critical body mass triggering younger menarche
,7. What happens to adolescents with weight and muscle mass during
puberty?: 50% of adult body weight is added and muscle mass increases
Increased muscle mass is more notable in boys while girls gain more fat in their
arms, legs, and trunk area
8. What is the psychological impact for girls who begin to gain more fat
during puberty?: Many girls have body image issues because of this going
against
Western societal views of ideal body proportions
9. How does being underweight or overweight effect puberty?: under-
weight individuals don't achieve puberty and overweight individuals start puberty
early 10. When does puberty typically end for girls and boys?: 16 for girls and
18 for boys
11. What does the hypothalamus do?: key regulatory center in the brain;
monitors body heat, water, nutrient levels, and regulates glands/hormones which
regulate sexual bx
12. What is the domino effect in regards to puberty?: various hormones are
released, triggering the development of secondary sex characteristics
13. What are the steps of the domino effect in puberty?: 1. Hypothalamus
slowly produces gonadatropin-releasing hormone (GnRH) during middle childhood
, and increases it during adolescence which is associated with leptin (protein) stored
in fat cells
2. GnRH stimulates the pituitary gland to produce gonadotropins (hormones)
such as the follicle-stimulating hormone (FSH) and the luteinizing hormone (LH)
3. Sex hormones are responsible for the development of secondary sexual
characteristics such as breast development, pubic hair growth, testicular growth
14 What triggers the increase in GnRH production during adolescence?:
Pre-pubertal growth spurts results in pre-teens achieving a threshold of body fat
(19% of body composition) and an increase in leptin levels which triggers
hypothalamus to increase GnRH production
15. What is the role of FSH and LH?: FSH stimulates maturation of ovarian
follicles and aids sperm production
LH triggers production of sex hormones, androgens, and estrogens into the
bloodstream
16. What are the first visible signs of secondary sex characteristics?:
Breast growth between ages 8 - 13
Testes and scrotal sac growth between ages 9.5 and 13.5
17. What is considered early puberty?: before age 10 for girls and before age
12 for boys
