Nociceptor

Nociceptors or pain receptors are cells in body tissues that respond to factors that cause pain. When pain occurs, a special nerve impulse is formed in the brain, which travels along the path from the receptor to the spinal cord. The result of this impulse is a change in the functioning of internal organs or, in other words, a reflex reaction.

The main function of pain sensitivity is to warn of possible injuries - this is evidenced by the fact that in the absence of nocicents in the body (for example, in Batian people) involved in professional sports, and also without the use of medications, there is a decrease in the risk of injury and damage. Without going into details about the structure of nerve cells, we will try to describe the reaction of nocicenters to stimulation in another language.

Body tissues can be injured, for example, when bruised due to a fall, and such a fall can occur due to lightning. Electricity can also provoke pain. All of the above factors can lead to damage to neurons (such as neurons in the spinal cord). Due to the fact that these neurons themselves have the ability to transmit information, other neurons - pain neurons - will eventually be used instead. These other neurons are initially activated reflexively by excitation of impulses transmitted to them from external sources. As a result, the body produces, in response to the resulting factor that caused the attack of pain, adrenaline and cortisol so that the person can eliminate the danger or continue to act blindly. Pain centers are activated regardless of a person’s desire, and the generated nerve signal temporarily blocks all other impulses that can lead to fear and panic. This is why our subconscious sometimes “talks” to people using the phrases “that’s all
