Adrenaline (epinephrine) and noradrenaline (norepinephrine) are sympathetic neurotransmitters that:
- increase excitatory neurotransmission in the central and autonomic nervous systems
- induce vasoconstriction (increasing blood pressure, shunting blood away from the surface of tissues, etc.)
- induce glycolysis through a cascade mechanism, whereby glycogen is quickly broken down into glucose in cells, increasing blood sugar levels to aid increased glucose metabolism in the brain and other organs
