3 Major systems of stress physiology: - ANS-Sympathetic Nervous System- response in
seconds
HPA Axis- response in minutes
Immune System- response in days
Acute Sleep Deprivation: - ANS-Short-term...
Impaired cognition
Increased risk of accidents
Adaptations to drug use: - ANS-Tolerance
Disruptions to homeostasis
Anhedonia- inability to experience pleasure from anything other than drugs
CRH & Stress of withdrawal
Hypofrontality- more impulsive, impaired decision making (less activity in frontal cortex)
Increased wanting, but not liking
Addiction - ANS-Uncontrollable cravings, compulsive behavior
Addictions are classified as: - ANS-Brain disorders
Adrenal Cortex - ANS-Produces cortisol (important to fight or flight response)
Adrenal Glands - ANS-Located just above kidneys
Two parts: adrenal cortex & adrenal medulla
Adrenal Medulla - ANS-Produces epinephrine and norepinephrine
Air pollution: - ANS-Can be indoor/outdoor
WHO considers air pollution the largest environmental threat
90% of the world lives in areas where air quality is not up to standards
Alcoholism is classified now as: - ANS-Psychiatric disorder
, Allostasis - ANS--Replaced homeostasis
Main Idea: There is adaptive flexibility of ranges in our body, your body will be able to
get back to these rages after experiencing a stressor
Anorexia nervosa - ANS-BMI Below 18
risk of mortality is 2-15%
Not getting enough nutrients
Anterior Pituitary - ANS-Releases ACTH
Antioxidants - ANS-Defend against free radicals
Little evidence they protect against disease
Studies are mixed and inconclusive
Asbestos - ANS-80% of mesothelioma cases are due to asbestos
Banned in 55 countries (not the US)
Atherosclerosis - ANS-Hardened growth in the arteries that blocks blood flow
Plaque can rupture which will cause a clot
Bad trans fats - ANS-Used to preserve products and give them a longer shelf life
Cookies, crackers, snacks
Basal Metabolic rate - ANS-- Minimal amount of caloric energy that is taken in that must
be devoted to those essential processes while the body is at rest
- 1/3 of calories are digested away, another 50% go to processes essential for life
- If you reduce caloric intake your BMR will change too, which is why you can't just keep
losing weight
Binge-eating - ANS--emotionally damaging
-excessive guilt
-body image distortions
BMI Measurement - ANS-Mass in pounds
------------------ x 703
Height in inches^2
