Norepinephrine
Along with dopamine and adrenaline, norepinephrine (NE) or sometimes noradrenaline (NA)belongs to the catecholamines. It is produced in cells of the locus coeruleus and in the adrenal medulla and usually has a stimulating effect. Noradrenaline is often associated with stress.

Adrenaline
Along with dopamine and norepinephrine, it belongs to the catecholamines. Adrenaline, also known as epinephrine, is the classic stress hormone. It is produced in the adrenal medulla and causes an increase in heart rate and heartbeat strength, thus preparing the body for increased stress. In the brain, adrenaline also acts as a neurotransmitter (messenger substance), where it binds to so-called adrenoreceptors.

Sympathetic nervous system
Part of the autonomic nervous system, whereby the sympathetic nervous system primarily transmits excitatory impulses – in contrast to its counterpart, the parasympathetic nervous system. For example, the sympathetic nervous system activates respiration, the heart, and circulation, but it also affects the smooth muscles of all internal organs. The sympathetic nervous system uses the neurotransmitters acetylcholine and norepinephrine.
