therefore, very often pain factors are called, but c-ceptors, but ciception is a term that charles sherington led to indicate a damaging effect and, uh, when the body signals to a person that it does not touch and it can be burned hot, then the person pulls his hand away. for this. we have signaling along nerve fibers so that we can very quickly avoid a damaging factor, and such fast fibers are called, and delta. and we also have slow fibers. this is a slow and such a spreading pain that is difficult for us to localize, and such pain occurs if the introduction is not acute, but it has been with us for a long time and we are constantly exposed to this effect, for example, if some of our organs become ill, they are destroyed in our tissue. and then we can already experience constant aching pain when a person perceives, uh, some stimuli, uh, which the body perceives as damaging , first of all, it depends on how the membranes of our cells have collapsed; our cells are covered with special such lipid membranes. and as soon as this lipid shell is destroyed. if tissue is damaged, they are released.
