General adaptation Syndrome
Han Selyre (1940)
- Subjected rats to stressors
- found that rate produced simular patterns of physical respnceses no matter what teh stressor was. He called this...
3) Exhausion Stage
1) Alarm Stage
Stressor is dealt with.
Both pathways are active do we get ready for 'Fight or flight'.
E.G-Pulse or breathing
If stressor persists SMP activity decreases but PAS path is maintained.
Since we have limited reasorces-->Bodys resistance is lowered
If still persists->Bodys responce system breaks down
->Illness, fatigue, anxiety, depression, impaired physical and mental abilities occur.
