    neurotransmitter and hormone involved in stress response and arousal

    Norepinephrine, also known as noradrenaline, is a neurotransmitter and hormone that plays a crucial role in the body's "fight or flight" response. It is produced in the adrenal glands and certain neurons, and it helps increase heart rate, blood pressure, and blood sugar levels, preparing the body to respond to stressful situations. In the brain, it is involved in attention, arousal, and mood regulation.
