Question

Peptides produced by nerve cells of brain which overcome the feeling of pain are?

• A. Encephalins
• B. Endorphins
• C. Growth hormone
• D. Insulin

Answer 1

The correct option is A Encephalins

Encephalin is a naturally occurring peptide that has potent painkilling effects and is released by neurons in the central nervous system and by cells in the adrenal medulla. Encephalins are known as endogenous opioids. These substances have powerful painkilling properties. The absence of pain in people who have sustained severe trauma is due to the rapid release and action of encephalins in response to the stressful stimulus of the injury.

So, the correct answer is 'Encephalins'.
