• Stress-a psychological and physiological reaction that occurs when perceived demands exceed
existing resources to meet those demands.
• Accessing a threat is primary appraisal and figuring out what to do about it secondary appraisal
• Fight or flight response-a set of physiological changes that occur in response to psychological or
physical threats
• General adaptation syndrome- a theory of stress responses involving stages of alarm, resistance
and exhaustion.
• The alarm reaction is the recognition of the threat and the physical response that comes with
that.
• Resistance is when one uses their physical or mental resources to respond to a stressor like
running away from a predator or study really hard the night before a test
• Exhaustion happen because an animal cannot stay at resistance forever so exhaustion happens
when the stressor has lessened
• Hypothalamic-pituitary-adrenal (HPA) axis- a neural and endocrine circuit that provides
communication between the nervous system (the hypothalamus) and the endocrine system
(pituitary and adrenal glands)
• When stress is perceived the hypothalamus releases a substance called corticotrophin-releasing
factor which stimulates the pituitary gland to release adrenocorticotrophic hormone which
triggers the release of cortisol.
• Cortisol- a hormone secreted by the adrenal cortex that prepares the body to respond to
stressful situations
• women are more likely to respond to with the tend and befriend response then the fight or
flight response
• Tend and befriend eas that whe soeoe ca’t deal with their stressor they look to other
resources to help like friends.
• Oxytocin-a stress-sensitive hormone that typically associated with maternal bonding and social
relationships
• Psychoneuroimmunology-is the study of relationship between immune system and nervous
system functioning.
• Coronary heart disease- a condition in which plaques form in the blood vessels that supply the
heart with blood and oxygen restricted blood flow,
