What is the key part of the body that never feels pain?

Body pain can appear at any time and be caused by several reasons, whether it is a blow, internal discomfort or a more serious condition. However, There is one part of the body that cannot feel pain: the brain.

Headaches are no different from any other pain and, depending on their intensity, should be treated without painkillers and with cold cloths, or with painkillers.

AS, How can headaches exist if the brain cannot feel pain? Even if you can’t feel it, the brain is the organ responsible for producing pain. This is because the surrounding structures can feel pain, while the brain is responsible for interpreting the signals it receives from nociceptors distributed throughout the body.

For example, During neurosurgery the brain can be treated simply with local anesthesia because it has no pain receptors.

“The fact that the brain cannot feel pain does not mean that we are beings incapable of perceiving it. On the contrary, brain tissue connects us with the external world through pain perception and, at the same time, interprets our internal environment through nociceptors of the organs. In short, the brain cannot feel pain, but we, as a whole, can”, explains the specialized medical site Mejor con Salud.

What are nociceptors?

Nociceptors are nerve endings located in the skin, joints, and some organs, although not in the brain. They are pain receptors that detect physical and chemical changes that could affect tissues.

Despite having a certain resistance to pain, when it is extremely intense the nociceptors send impulses to the spinal cord and, subsequently, to the brain. Finally, The brain receives the data and issues a response: pain.
