Chapter 7: The Autonomic Nervous System and Hormones

Question 1

Autonomic Nervous System

Answer 1

parasympathetic and sympathetic
responsible for flight or fight
prepares for vigorous activity
prepares for rest and digest

Question 2

Sympathetic

Answer 2

increase in bp and hr
increase in skin conductance
inhibits digestion
inhibits sexual arousal
increase breathing rate

Question 3

Parasympathetic

Answer 3

body needs to rest+ grow/digest
energy for procreation
blood to the periphery
insulin!!
salivation
slow breathing

Question 4

simultaneous responses

Answer 4

retching (contracting the intestines + retching)

Question 5

Interbeat Interval

Answer 5

the mean ms between the R peaks of an EKG signal

Question 6

systolic bp

Answer 6

contraction of ventricles

Question 7

Diastolic BP

Answer 7

relaxation of ventricles

Question 8

Electrodermal activity

Answer 8

increased speed of electrical conductivity by the skin from increased sweating
very quick!

Question 9

Respiratory Sinus Arrhythmia

Answer 9

heart rate comparison between inhaling and exhaling
used to assess the PSN influence on the heart

Question 10

PSN and the heart

Answer 10

slows the heart rate to maintain homeostasis

Question 11

William James

Answer 11

different emotional feelings may be associated with different profiles of activity in the body

Question 12

Autonomic Specificity Hypothesis

Answer 12

each emotion has a distinct ANS response

Question 13

ASH test

Answer 13

participants posed facial expressions and heart rate, skin conductance, finger temp, etc
conclusions: not really conclusive, arousal and valence differences may be more representative of the data’s slight differences

Question 14

Epinephrine + Cortisol

Answer 14

key for stress

Question 15

Hans Seyle

Answer 15

among diseases, almost all have fever, low energy, fatigue, low sex drive + appetite
injected rats to see what was up but he was kind of bad at it lmao

Question 16

General Adaptation Syndrome

Answer 16

alarm, resistance, and exhaustion

Question 17

Seyle’s definition of Stress

Answer 17

the nonspecific response that your body makes to any demands on it

Question 18

Seyle’s definition of Alarm

Answer 18

first stage, with brief high arousal and epinephrine + cortisol is secreted

Question 19

Seyle’s definition of Resistance

Answer 19

prolonged, moderate arousal where the body secretes cortisol in case there is danger

Question 20

Seyle’s definition of Exhaustion

Answer 20

weakness, fatigue, loss of appetite, lack of motivation, immune system is less active

Question 21

Social Readjustment Rating Scale

Answer 21

bending metal metaphor, though it has its issues

Question 22

McEwen’s definition of Stress

Answer 22

an event(s) that are interpreted as threatening to an individual and which elicit physiological/behavioural responses

Question 23

What’s involved in Stress

Answer 23

the heightened activity of the HPA axis
hypothalamus sends signals to the pituitary gland, which stimulates the secretion cortisol after travelling through the bloodstream

Question 24

Leukocytes

Answer 24

white blood cells
prolonged stress associated w/ decreased production

Question 25

Cytokines

Answer 25

stimulate the brain to initiate adaptive responses (immune) like fever, sleepiness, decreased appetite, etc

Question 26

Hippocampus

Answer 26

is at risk with prolonged stress because the body is more likely to take in toxins
