PSYCH 140 MODULE 6/60QUESTIONS AND ANSWERS
(A+)
Adolescence - =The onset of adolescence is marked by
puberty. The ending is a little more difficult to define
since adolescence ends when an adult role is assumed.
In many societies today, assuming a full adult role is
frequently pushed back, usually so that educational and
personal pursuits can first be obtained.
-Puberty - =In North America, the average age for this
growth spurt is around age 10 for girls and age 12 ½ for
boys.
-When do boys and girls typically stop growing? - =Girls
typically finish growing by age 16, while boys may
continue to grow until nearly age 18.
-During puberty... - =adolescents typically add nearly 50
percent of their adult body weight. Muscle mass also
increases at this time for both boys and girls. However,
this increase in muscle mass is much more notable in
boys, while the female pubertal growth spurt results in
girls adding fat to their arms, legs, and trunk area.
-Domino Effect occurs in Adolescence - =various
hormones being released; these trigger the
development of secondary sex characteristics.
1. The hypothalamus slowly produces GnRH, or
gonadatropin-releasing hormone, beginning in middle
childhood. Production really ramps up after middle
, childhood and is thought to be associated with the
protein leptin, which is stored in fat cells.
2. When GnRH reaches the pituitary gland, it stimulates
the gland to produce hormones called gonadotropins,
which include follicle-stimulating hormone (FSH) and
luteinizing hormone (LH). FSH stimulates maturation of
ovarian follicles as well as aids sperm production. LH
triggers production of sex hormones, androgens and
estrogens, into the bloodstream.
3. These sex hormones are responsible for the
development of secondary sexual characteristics, such
as breast development, pubic hair growth, testicular
growth, etc. At this point and afterward, males have
more androgens, and females have more estrogens.
-Hypothalamus - =The hypothalamus in the brain is a
key regulatory center in the brain. In addition to
monitoring body heat, water, and nutrient levels, it also
regulates glands and hormones given its role in also
regulating sexual behavior. The hypothalamus slowly
produces GnRH, or gonadatropin-releasing hormone,
beginning in middle childhood.
-GnRH - =gonadatropin-releasing hormone
- produced by the hypothalamus is sent to the pituitary
gland to produce gonadotrophin hormones.
-FSH - =follicle-stimulating hormone
- FSH stimulates maturation of ovarian follicles as well
as aids sperm production.
-LH - =luteinizing hormone
