Which autonomic neurons release norepinephrine as a neurotransmitter?
Autonomic Nervous System
The autonomic nervous system is divided into the sympathetic and parasympathetic nervous system. The sympathetic nervous system is known as the fight or flight reaction to stress while the parasympathetic nervous system is in charge during periods of rest.
Answer and Explanation:
The sympathetic nervous system is in charge of the fight or flight response during emergencies or stressful situations. The adrenal medulla is part of the adrenal glands which are responsible for secreting catecholamines (hormones) to deal with the stress. These catecholemines are epinephrine and norepinephrine. Norepinephrine is also a neurotransmitter and is released from the adrenal glands to increase the heart rate, blood pressure, cardiac output, and blood sugar levels during periods of stress. Neurotransmitters send impulses from nerves to other parts of the body.
