Norepinephrine is made from dopamine in the medulla of the adrenal gland.

epinepherine and norepinephrine

The adrenal gland makes and secretes norepinephrine and also converts some norepinephrine into epinephrine and secretes that.

Norepinephrine is released from the sympathetic nervous system. Norepinephrine is a stress hormone which affects parts of the brain and causes the heart to beat more rapidly.
