The Sympathomedullary Pathway
1. Immidiate stressors activate the SNS. The SNS prepares the body for fight or flight by the release of neurodreniline.
2. This is transported to the adrenal medulla via the bloodstream and causes the release of adreniline.
3. Adreniline then increases oxygen and glucose levels and suppresses non-emergancy bodily functions.
The Pituitary-Adrenal System
1. The hypothalimous percieves higher stressors in the brain and releases CRF.
2. The CRF arrives at the pituitary glad and causes the release of ATCH which is transported via the bloodstream to the adrenal cortex.
3. The adrenal cortex then releases Cortisol which has a range of effects on the body. Positive ones such as lessened response to pain and negetive ones such as the suppression of the immune system.
