Epinephrine and norepinephrine are released from the adrenal medulla in response to sympathetic nervous system activation. The release is triggered by the neurotransmitter acetylcholine, which is released from the preganglionic sympathetic fibers that synapse with the medullary cells. This stimulation of the adrenal medulla is part of the fight or flight response, which prepares the body for stressful situations.
