The perform of the immune and nociceptive units is based on recognizing damaging and/or dangerous stimuli. Their response performs a vital function in blocking tissue damage and restoring homeostasis. The dysregulation of these interactions could underlie the pathogenesis of quite a few inflammatory illnesses. The interactions concerning the immune method and nociceptive neurons occur in just both of those peripheral web sites of harm along with inside the central nervous program.

The ''pain'' concept is coded while in the sample and frequency of impulses while in the axons of the principal afferent nociceptors. You will find a direct relation amongst the intensity from the stimulus and the frequency of nociceptor discharge (Determine seven-three).
