Describe how the hypothalamus, the brain stem, and the reticular activating system are involved in the responses to stress. Provide two classic physiological stress responses from each of the above system
Homework Answers
Stress is biological and psychological response of our body when we feel that we can't handle or deal with situation.
HYPOTHALAMUS,also known as brain stem is in charge for stress response.It sends signal to 2 system when there is condition of stress-
1.it send signal to pituitary gland which secrete adrenocorticotropic hormone which further activate adrenal gland which secrete cortisol,the stress hormone.Cortisol maintain sugar level (break stored glycogen of liver into sugar and release it in blood) so that body can deal with stress.
2.Also it send signals to adrenal medulla which will secrete hormone adrenaline for fight or flight response.
Reticular Activating System is located in mesopons.It is responsible for sleep-awake cycle It also take part in fight or flight response and give alertness .
