Adrenergic Neurons Release _______

Question

Adrenergic neurons release _______.
A) endorphins
B) serotonin
C) dopamine
D) norepinephrine

Accepted Answer

Adrenergic neurons are nerve cells that release norepinephrine. Norepinephrine is a neurotransmitter that plays a key role in the "fight or flight" response in the sympathetic nervous system. It is involved in increasing heart rate, blood pressure, and respiration, among other effects. Endorphins are released by the body in response to pain or stress and can have a pain-relieving and mood-lifting effect. Serotonin and dopamine are other neurotransmitters involved in mood regulation and reward pathways in the brain.
