Epinephrine's binding to these receptors triggers a number of metabolic changes. Norepinephrine may have different effects on migraines and other types of headaches. For example, norepinephrine levels are several times higher than normal in the blood of people with cluster headaches. In rats, norepinephrine in the protective layer around the brain triggered headache symptoms [27, 28].
Epinephrine is synthesized from norepinephrine within the adrenal medulla, which are small glands associated with the kidneys. Preganglionic fibers of the sympathetic nervous system synapse within the adrenals.
