Physical and Cognitive Development in Adolescence
When does adolescence begin?
onset of puberty
When does it end?
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.
(true or false) The idea of a transition period between childhood and adulthood did not always
exist.
true
Historically, children, after perhaps completing a rite of passage, were considered adults.
However, the period of adolescence is now widely accepted, at least in most post-industrial
cultures.

The onset of adolescence is marked by what?
puberty
A. Puberty
When does the pubertal growth spurt usually begin in early adolescence?
In North America,
the average age for growth spurt =
around age 10 for girls age 12 ½ for boys.
Girls typically finish growing by age 16
boys may continue to grow until nearly age 18.
-adolescents typically add nearly 50 percent of their adult body weight.
-muscle mass also increases at this time for both boys and girls.

-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.
What triggers a domino effect to occur during puberty?
various hormones being released; these trigger the development of secondary sex characteristics.
What is considered the key regulatory center in the brain that monitors body heat, water, nutrient
levels, and regulates glands and hormones/ sexual behavior?
The hypothalamus
summary of the domino effect
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
pre-pubertal growth spurts result in pre-teens achieving a certain threshold of body fat
(approximately 19 percent of total body composition).

Leptin levels subsequently increase, and this triggers the hypothalamus to start greater GnRH
production
GNRH is then sent to the pituitary gland in the brain.
GnRH reaches the pituitary gland, it stimulates the gland to produce hormones called
gonadotropins, which include follicle-stimulating hormone (FSH) and luteinizing hormone (LH)
sex hormones are responsible for the development of secondary sexual characteristics, such as
breast development, pubic hair growth, testicular growth, etc.
FSH
stimulates maturation of ovarian follicles as well as aids sperm production
LH
triggers production of sex hormones, androgens and estrogens, into the bloodstream.
