Question

Which one of the following does not act as a neurotransmitter?

• A. Acetylcholine
• B. Epinephrine
• C. Norepinephrine
• D. Cortisone

Answer 1

The correct option is D

Cortisone

Cortisone is one of the main hormones released by the adrenal gland in response to stress. It suppresses the immune system, thus reducing inflammation and attendant pain and swelling at the site of the injury.
Epinephrine and Norepinephrine are neurotransmitters that are secreted in response to stress of any kind and during emergency situations and are called emergency hormones or hormones of Fight or Flight.
Acetylcholine is an organic chemical that functions in the brain and body of many types of animals, including humans, as a neurotransmitter—a chemical released by nerve cells to send signals to other cells.
