Detailed explanation-1: -The adrenal medulla is the inner portion of the adrenal gland. It regulates and secretes both epinephrine and norepinephrine in response to stress and other imbalances in the body, such as low blood pressure.

Detailed explanation-2: -After the amygdala sends a distress signal, the hypothalamus activates the sympathetic nervous system by sending signals through the autonomic nerves to the adrenal glands. These glands respond by pumping the hormone epinephrine (also known as adrenaline) into the bloodstream.

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 and noradrenaline are two separate but related chemical messengers. They are produced in the centre (medulla) of the adrenal glands and noradrenaline is also produced in some nerve cells (neurons) of the central peripheral nervous system.

Detailed explanation-5: -The sympathetic nervous system (SNS) of the CNS that is involved when a stressor is encountered is the SNS stimulation of the adrenal glands, which, releases the catecholamines epinephrine (adrenaline) and norepinephrine (noradrenaline).
