Detailed explanation-1: -Adrenaline is responsible for the fight-or-flight reaction to a threat, and it triggers specific processes in the body. For example, it might make the body send extra oxygen to the lungs to aid a person to run away. As well as allowing a quick escape from danger, adrenaline has other effects on the body.
Detailed explanation-2: -The hormones produced by the adrenal medulla are called catecholamines. They act as hormones and as neurotransmitters (chemical messengers in the nervous system). They manage the body’s response to stress. The 2 more important catecholamines are epinephrine and norepinephrine.
Detailed explanation-3: -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.
Detailed explanation-4: -Adrenaline is released by the adrenal glands in the body. Hypothalamus sends the signal of releasing adrenaline whenever there is a situation of flight, fright, or fight.
