Which of the following represents the correct order in terms of speed of response to an acute stressor (fastest first).
| | a) | direct sympathetic neuron activation of target tissue; cortisol release; adrenaline from the adrenal gland acts on target tissue | |
| | b) | cortisol release; adrenaline from the adrenal gland acts on target tissue; direct sympathetic neuron activation of target tissue; | |
| | c) | cortisol release; adrenaline from the adrenal gland acts on target tissue; direct sympathetic neuron activation of target tissue | |
| | d) | direct sympathetic neuron activation of target tissue; adrenaline from the adrenal gland acts on target tissue; cortisol release | |
| | e) | cortisol release; direct sympathetic neuron activation of target tissue; adrenaline from the adrenal gland acts on target tissue | |
The correct option is \"b\" and \"c\" (In this question the option \'\'b\" and \"c\" is same). When a person encounters with a stressfull situation then the hypothalamus of the person send signals to pituitary gland. Pituitary gland secrets ACTH (Adreno cortico trophic hormone), which activates adrenal gland due to which cortisol release from the adrenal cortex of adrenal gland. Then adrenaline releases and activates the sympathetic neurons of the atrget tissue.
