BEHAVIOR AND COGNITIVE
NEUROSCIENCE: UNIT 3 QUESTIONS
WITH 100% CORRECT ANSWERS {
GRADED A+}
Hormones - ✔✔chemicals that travel through the bloodstream to act on target
tissues
Hormones affect many aspects of behavior and body: - ✔✔-growth, wake-sleep
cycles, mood, apoptosis, the immune system, metabolism, hunger, reproductive
cycle
-preparation of the body for mating, fighting, fleeing, and other activity
-preparation of the body for puberty, parenting, and menopause
-production and release of other hormones
endocrine glands - ✔✔release hormones within the body
,exocrine glands - ✔✔use ducts to secrete fluid outside the body, such as tears and
sweat
types of chemical communication: - ✔✔synaptic, endrocrine, pheromone,
allomone
synaptic - ✔✔transmitters across the cleft
endrocrine - ✔✔hormones released into the bloodstream to selectively affect
distant target tissues
pheromone - ✔✔chemicals released outside the body to affect other individuals of
the same species
allomone - ✔✔chemicals released outside the body to affect individuals of
another species
neuroendocrine cells - ✔✔neurons that release hormones into the blood
hormone categories: - ✔✔peptide hormones, amine hormones, and steroid
hormones
peptide hormone - ✔✔short string of amino acids
amine hormone - ✔✔modified version of a single amino acid
, steroid hormone - ✔✔derived from cholesterol, made of four rings of carbon
atoms
peptide and amine hormones mechanism of action: - ✔✔both bind to specific
receptors on the surface of a cell and activate second messengers inside the cell
(seconds-minutes)
steroid hormones mechanism of action: - ✔✔cross the cell membrane and bind to
receptors inside the cell
the steroid-receptor complex binds to specific regions of DNA and controls
expression of specific genes (hours-days-years)
mechanism of action for hormones: - ✔✔one hormone often acts on multiple
target organs. Different effects due to different receptors, but also due to different
cell types
pituitary gland location - ✔✔it is connected to the hypothalamus via the pituitary
stalk
Two parts of the pituitary: - ✔✔anterior and posterior
posterior pituitary - ✔✔releases hormones but does not make them
