BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The neurotransmitter noradrenaline also reaches your adrenal gland, which releases the hormones adrenaline (epinephrine) and noradrenaline (norepinephrine). These hormones travel through your blood to all parts of your body. They reach your eyes, heart, airways, blood vessels in your skin and your adrenal gland again.

Detailed explanation-2: -Instead, since its chemical composition resembles norepinephrine very closely, epinephrine stimulates norepinephrine receptors both in the brain as well as peripherally. In fact, while norepinephrine is primarily a neurotransmitter, epinephrine is primarily a hormone.

Detailed explanation-3: -Neural Stimuli Here, neuronal signaling from the sympathetic nervous system directly stimulates the adrenal medulla to release the hormones epinephrine and norepinephrine in response to stress.

Detailed explanation-4: -Adrenaline (epinephrine) is a hormone your adrenal glands make to help you prepare for stressful or dangerous situations. Adrenaline rush is the name for the quick release of adrenaline into your bloodstream. This gets your body ready for a “fight or flight” response.

Detailed explanation-5: -The catecholamines, norepinephrine and epinephrine (formerly named noradrenaline and adrenaline) are released from the adrenal gland and neurons in the brain.
