Question

Adrenaline is equivalent to which neurotransmitter?
A. ABA
B. Serotonin
C. Epinephrine
D. None of the above

Answer 1

Hint: Adrenaline, commonly known as epinephrine, is a hormone and drug that plays a role in visceral function regulation. The adrenal glands and a small number of neurons in the medulla oblongata ordinarily create adrenaline.

Complete answer:
Neurotransmitters are chemical messengers that transfer a signal from a neuron to a target cell, which can be another neuron, muscle cell, or gland cell, across the synapse. Neurotransmitters are chemical compounds produced by neurons with the sole purpose of transmitting a message.
Adrenaline's main effects include boosting heart rate, blood pressure, expanding lungs' air passageways, enlarging the pupil in the eye, shifting blood to muscles, and modifying the body's metabolism to maximize blood glucose levels.
The hormone epinephrine, often known as adrenaline, is produced by the medulla of the adrenal glands. Epinephrine is released into the bloodstream in response to strong emotions like fear or anger, causing an increase in heart rate, muscle strength, blood pressure, and sugar metabolism. The flight or fight response is a physiological response that prepares the body for vigorous exercise.

So, option C is the right answer.

Additional information
In the developmentally developed mammalian central nervous system, GABA is the most important inhibitory neurotransmitter. Its main function is to reduce neuronal excitability across the nervous system.
Serotonin has a complex and comprehensive biological function, affecting mood, cognition, reward, learning, memory, and a variety of physiological functions like vomiting and vasoconstriction.

Note: Severe allergic reactions (anaphylaxis) to insect stings or bites, foods, medications, and other allergens are treated with epinephrine injection. A person with a history of severe allergic reactions may keep epinephrine auto-injectors on hand for self-injection.
