Which group of neurotransmitters includes epinephrine and dopamine?

• A. Serotonin
• B. Endorphins
• C. Catecholamines
• D. Estrogens

Answer: (C)

The group of neurotransmitters that includes epinephrine and dopamine is known as catecholamines. This classification is important because catecholamines are derived from the amino acid tyrosine and play significant roles in the body's response to stress, regulation of mood, and various physiological processes. Epinephrine, also known as adrenaline, is crucial for the "fight or flight" response, increasing heart rate and energy availability during stressful situations. Dopamine is a key neurotransmitter involved in reward, motivation, and the regulation of mood and movement. By grouping these two neurotransmitters under catecholamines, it highlights their structural similarities and related functions within the nervous system. Understanding catecholamines also allows for better comprehension of disorders related to these neurotransmitters, such as Parkinson's disease, which is linked to dopamine deficiency, or issues related to stress and anxiety involving epinephrine. Consequently, recognizing catecholamines helps in grasping the broader implications of neurotransmitter function in psychological and physiological health.
