HOW DO PAINKILLERS KNOW WHERE THE PAIN IS?

 

How do painkillers work?

Whenever I get hurt and feel pain, my mom gives me painkillers but the question that comes in my mind is that how do painkillers know where the pain is? Now when I know this answer I am here to share with you.

First you should know the definition of pain. Pain is an uncomfortable feeling in any of the body parts and painkillers are medicines which give us relief from pain.

If you are working with a needle and it gets stuck in your finger, you remove your finger because you feel the pain. When we hurt our self a chemical named Prostaglandin is released. Then nerve endings give the message to your brain or in terms of tech – a sort of notification that where the pain is and how much it hurts.

When we swallow painkillers, we feel well. It is because the pain killer stops the nerve endings to give a message to the brain. We do not know it is paining and think we are well now. Painkillers don’t let us know it’s paining so that we can rest. The repairing of the injury is done by the body itself.

The rays of sun that fall on moon undergo reflection and when the reflected rays reach our eyes we are able to see the moon and perceive that moon is shining. The same is responsible for the different shapes that the moon acquires. The phases of moon are in being due to variation of the area on which the light is falling. The area of the ...
