Document Summary

Inhibit in ammation and immunity (they can be distracting if you are running from a threat). This image summarizes the two different hormonal mechanisms that we can use to respond to stress. On the left we see short term stress and on the right we see long term stress. Short term stress symptoms: sweaty, shaky, increased heart rate, dilated pupils . Long term stress has different symptoms: all the things you feel during study period before. The short term stress pathway has hormone epinephrine/adrenaline. Both have to do with adrenal glands (pyramid shaped structures on the kidneys). Crh: released by hypothalamus triggers the release of acth (adrenocorticotropic hormone) from anterior pituitary. And this leads to the release of cortisol from the adrenal cortex. Trh is release by hypothalamus and triggers thyroid stimulating hormone. Epinephrine = adrenaline. it is controlled by a neurological pathway. Breakdown of adipose tissue > glycerol and fatty acids.
