Answer 2

Explanation:

Opioid peptides produced by the body are encephalins, B-endorphin, and dynorphins.

Encephalin is a pentapeptide involved in regulating nociception in the body.

The encephalins are termed endogenous ligands, as they are internally derived and bind to the body's opioid receptors.

Encephalin is also considered a neuropeptide, which in the human body performs as an important signalling molecule in the brain.

Encephalins are found in high concentration in the brain as well as in the cells of the adrenal medulla

In response to pain, norepinephrine, a hormone that is activated in fight-or-flight response is released along with endorphins. .Hence, Natural pain killers produced by nerve cells of the brain are Encephalins.

So, the correct answer is 'Encephalins'.
