In stressful circumstances, The body react if there are build ups in the production of hormones like adrenalin and cortisol that yields an alteration of heart rate and metabolism to make better performance (Peters, M. 2006).
Stress reaction is triggered when there is an activation of stressor in the hypothalamus. In this essay the stressor identified is the patient waiting to be seen in a clinic feeling stressed.
When patient perceive that they are in frightening or uneasy situation and that they do not have the capacity to deal successfully, the neurons carry the messages to the cerebral cortex which is the area of the brain where thinking process comes, to determine the trouble.
