Question

Name the hormone released during the following events$:$

A frightened person

• A. Testosterone
• B. Thyroxine
• C. Adrenaline
• D. Growth hormone

Answer 1

The correct option is C Adrenaline

Adrenaline, also known as epinephrine, is a hormone, neurotransmitter, and medication. Adrenaline is normally produced by both the adrenal glands and certain neurons. It plays an important role in the fight-or-flight response by increasing blood flow to muscles, the output of the heart, pupil dilation response, and blood sugar level. It does this by binding to alpha and beta receptors. It is found in many animals and some single cell organisms. Hence, the hormone released by a frightened person is Adrenaline.

So, the correct answer is 'Adrenaline'.
