Alarm Reaction
- The initial stage in the body's response to stressful stimuli, characterized by adaptive physiological changes, such as increased hormonal activity and increased heart rate
- Analgesia
- Absence of pain in response to stimulation which would normally be painful
-
B Lymphocytes
- make antibodies against soluble antigens
- Constant non-stop stress
- eat less
- CRH
- suppresses appetite (fast acting)
- Diabetes
-
- Hormones released during stress cause glucose and fatty acids to be released into bloodstream
- The body becomes unresponsive to insulin

- During stress:
-
- Glucocorticoids damage the hippocampus
- Amygdala activation can disrupt hippocampus
- Neural networks get disconnected
- Decreased glucose to neurons

-
- Affects the synthesis, release, efficacy, and breakdown of serotonin
- Immunosuppression
- Lethargy
-
Exercise results in:

- Body arousal
- Warmth
- Muscle relaxation
- Sound sleep
- Exhaustion
- the result of a period of expending too much effort at work while having too little recovery

-
General Adaptation Syndrome
- the body has a natural, adaptive response to stress that is composed of three stages: alarm, resistance, exhaustion
-
Glucocorticoids
- affect metabolism and have anti-inflammatory and immunosuppressive effects
- Hyperalgesia
- An increased response to a stimulus that is normally painful

- Macrophages
- phagocytize (engulf and then digest) cellular debris and pathogens either as stationary or mobile cells, and to stimulate lymphocytes and other immune cells to respond to the pathogen
