Detailed explanation-1: -Cortisol, the primary stress hormone, increases sugars (glucose) in the bloodstream, enhances your brain’s use of glucose and increases the availability of substances that repair tissues. Cortisol also curbs functions that would be nonessential or harmful in a fight-or-flight situation.

Detailed explanation-2: -Adrenaline is a hormone released from the adrenal glands and its major action, together with noradrenaline, is to prepare the body for ‘fight or flight’.

Detailed explanation-3: -Epinephrine’s major action is in its role as a hormone. Epinephrine is released by your adrenal glands in response to stress. This reaction causes a number of changes in your body and is known as the fight-or-flight response.

Detailed explanation-4: -Effects of epinephrine stimulation are especially evident during stress reactions, and epinephrine is one of the major hormones involved in the stimulation of the sympathetic nervous system.

Detailed explanation-5: -Adrenaline is produced in the medulla in the adrenal glands as well as some of the central nervous system’s neurons. Within a couple of minutes during a stressful situation, adrenaline is quickly released into the blood, sending impulses to organs to create a specific response.
