What was going on in your endocrine system before the chair dropped, due to longer term stress about your exam? Do you think this affected your response to the chair? Solution Thanks for the question. I am assuming here that the individual was sitting on the chair when the chair dropped. Thus the endocrine response of the body during this time is being evaluated. 1. Long term stress about the exam can effect the insulin production by the pancreas . The insulin production, if increased can cause hypoglycemia resulting in fainting and chair drop. Decreased insulin production will result in hyperglycemia which can again cause dizziness and fainting and can cause you to fall from the chair. 2. Epinephrine and norepinephrine levels are increase. This can cause an increase in heart rate and blood pressure which can also cause dizziness and fainting and cause the chair drop. Regards.
