Hormones And Behavior Final Exam Psych 4644 Questions
And Accurate Answers
what is stress - ANSWER state of threatened homeostasis/disruption in homeostatic
balance
What causes the imbalance in homeostasis? - ANSWER the stressor
what are different types of stressors? - ANSWER environmental (high temps),
physiological (insufficient food availability), psychological (social subordination), in
developed countries stressors are typically psychological (finals, personal
relationships, Paying bills)
What is the stress-response? - ANSWER The bodies response to the imbalance
what is the stress response supposed to do? - ANSWER reestablish homeostasis
through physiological and behavioral responses
are there specific stress responses? - ANSWER No, they are all the same
What is the pathway for stress? - ANSWER sensory info sent to amygdala that interprets
the info and when danger is present then a signal is sent to the hypothalamus
what are the two endocrine systems that are responsible for the stress response? -
ANSWER 1) sympathetic nervous system 2) hypothalamic pituitary-adrenal axis (HPA)
what hormones do the sympathetic nervous system activation cause the release of? -
ANSWER Catecholamines, Epinephrine, norepinephrine
where does the sympathetic nervous system cause the release of hormones from? -
ANSWER Adrenal medulla
what hormones is the HPA releasing the the stress response? - ANSWER Cortisol from
the adrenal cortex
what is the pathway of the sympathetic nervous system response? - ANSWER
Hypothalamus projects to the preganglionic sympathetic neurons in the spinal cord
which is projected to the sympathetic chain. Post-ganglionic cells project to every organ
that uses NE and releases it. Preganglionic neurons project to the adrenal medulla to
secrete epinephrine and NE into blood
what are the processes that are inhibited by the sympathetic nervous system? -
ANSWER Inhibition of saliva, inhibits digestion
what other processes are affected by sympathetic activation? - ANSWER Airways are
relaxed, heartbeat speeds up and blood vessels are constricted
