1. Higher brain centres activate hypothalamus. 2. Hypothalamus releases CRF. 3. Pituitary gland releases ACTH. 4 Adrenal Cortext releases corticosteriods into bloodstream. 5. Corticosteriods cause fight - or - flight.

Pituitary-adrenal system evaluation
Fight or flight is a male stress response, and tend and befriend is a female stress response.
2 of 5
Sympathomedullary pathway
1. Activation of SNS causes bodily arousal. 2. SNS also activates adrenal medulla. 3. Releases adrenaline and nonadrenaline. 4. Both support sympathetic activation.

Sympathomedullary pathway evaluation
Stress response adaptation to stessors faced by ancestors, and fight or flight resonse prepared the body for energy expenditure

Tip to help you remember the pathways
The Pituitary-adrenal system involves the adrenal cortext - whereas the sympathomeduallary pathway involves the adrenal medulla.
