portage lifespan development module 6
1. average age for pubertal growth spurt for girls < Ans > 10
2. average age for pubertal growth spurt for boys < Ans > 12.5
3. girls typically finish growing by age < Ans > 16
4. boys continue growing until < Ans > 18
5. during pubertal growth spurts, adolescents add nearly of their adult
body weight < Ans > 50%
increase in muscle mass more noticeable in boys
6. girls tend to add fat where during puberty < Ans > arms, legs, trunk
many girls dislike their body at this time
7. what type of effect occurs during puberty as hormones are being released-
< Ans > domino effect
various hormones trigger the development of secondary sex characteristics
8. role of hypothalamus in puberty < Ans > - regulates glands and hormones
- regulate sexual behavior
- produces GnRH (gonadatropin-releasing hormon) in middle childhood; assoc with protein
leptin stored in fat cells
The current hypothesis is that pre-pubertal growth spurts result in pre-teens achiev- ing a
certain threshold of body fat (approximately 19 percent of total body composi- tion). Leptin
levels subsequently increase, and this triggers the hypothalamus to start greater GnRH
production.This hypothesis is supported by evidence of under-weight individuals not
achieving puberty and overweight individuals being more likely to start puberty early.

10. what happens after the hypothalamus sends gonadotropin-releasing hor- mone to
the pituitary master gland? < Ans > pituitary releases FSH, LH
Then there is increased production of sex hormones in the bloodstream
11. When GnRH reaches the pituitary gland, it stimulates the gland to produce
hormones called gonadotropins, which include < Ans > < Ans > follicle-stimulating
hormone
