Lesson 7: Adolescence Flashcards
(72 cards)
The process by which a person attains sexual maturity and the ability to reproduce.
Puberty
The organs necessary for reproduction, such as ovaries, testes, uterus, etc. These enlarge and mature during adolescence.
primary sex characteristics
Signs of sexual maturation like breast development, voice changes, and growth of body hair that do not directly involve the sex organs.
secondary sex characteristics
It involves hormonal changes that trigger the development of primary and secondary sex characteristics.
Puberty
It occurs between ages 6 and 8, when adrenal glands secrete increasing levels of androgens (dehydroepiandrosterone or DHEA).
Adrenarche
It is the maturing of the sex organs, triggering a second burst of DHEA production.
Gonadarche
It is a rapid increase in height, weight, and muscle mass during puberty, just before reaching full sexual maturity.
Adolescent growth spurt
Girl’s first menstrual period, indicating the onset of sexual maturity.
Menarche
boy’s first ejaculation, indicating the onset of sexual maturity.
Spermarche
When do most girls experience a growth spurt compared to boys?
Most girls experience a growth spurt 2 years earlier than boys, so between ages 11 and 13, girls tend to be taller, heavier, and stronger than boys the same age.
It contributes to faster body growth, oilier skin, and the development of body odor.
Adrenarche
What is the average age of menarche?
around 12-13 years
What are the Pubertal timing
Secular trend, influences, race/ethic differences, timing matters
How do race/ethnic differences affect pubertal timing?
On average, Black and Hispanic girls start puberty earlier than White and Asian girls, and Black and Hispanic boys mature faster than White boys.
What risks do early maturing girls face?
Increased risk for problems like depression, eating disorders, substance abuse, and early sexual activity.
What are the effects of early maturation in boys?
Early maturing boys face some risks but also tend to be taller and more athletic.
What challenges do late maturing youth face?
Late maturing youth face psychosocial challenges but not the same health risks.
What is the impact of increased white matter in the adolescent brain?
It permits faster communication between brain regions.
What happens to gray matter during adolescence?
Gray matter increases then prunes, leading to a more efficient but still maturing cortex.
Which brain regions mature first during adolescence?
Subcortical regions mature first, which are linked to increased sensation-seeking.
Which area of the brain matures last in adolescents?
The prefrontal cortex matures last, which is important for impulse control and planning.
What is a common issue with physical activity among teens?
Teens often do not get enough exercise.
What can poor exercise habits in adolescence lead to?
They may result in poor lifelong health habits and early death in adults.
What health risks can insufficient physical activity impact?
It can impact the risk for obesity, diabetes, and heart disease.
