Adrenaline vs. Adrenalin

By Jaxson

  • Adrenaline

    Adrenaline, also known as adrenalin or epinephrine, is a hormone, neurotransmitter, and medication. Epinephrine is normally produced by both the adrenal glands and certain neurons. It plays an important role in the fight-or-flight response by increasing blood flow to muscles, output of the heart, pupil dilation response, and blood sugar level. It does this by binding to alpha and beta receptors. It is found in many animals and some single cell organisms. Napoleon Cybulski first isolated epinephrine in 1895.

  • Adrenaline (noun)

    epinephrine, the hormone and neurotransmitter.

  • Adrenaline (noun)

    a hormone secreted by the adrenal glands that increases rates of blood circulation, breathing, and carbohydrate metabolism and prepares muscles for exertion

    “performing live really gets your adrenaline going”
