Pain is the most prominent member of a class of sensations known as bodily sensations, which includes itches, tickles, tingles, orgasms, and so on. The TRP channel family is of interest because several members have been implicated in nociceptor signal transduction.Noxious cold and noxious heat stimuli are detected by A and C fiber nociceptors.

Nociception refers to a signal arriving at the central nervous system as a result of the stimulation of specialised sensory receptors in the peripheral nervous system called nociceptors. Kindle Edition. c. proprioception. High-threshold receptors exclusively innervate organs from which pain is the only conscious sensation (i.e., ureter, kidney, lungs, heart), but are relatively few in organs that provide innocuous and noxious sensations (e.g., colon, stomach, and bladder), innervated mostly by low-threshold receptors.

Valid means having a sound basis in logic or fact; reasonable or cogent. In human microneurographic studies, injection of ATP activated 60% of mechano-responsive and mechano-insensitive C-nociceptive fibers without sensitizing these fibers to mechanical or heat stimuli. Free nerve endings terminating in the skin are the machinery for signaling local mechanical, thermal, and chemical changes. C fiber afferents can be divided into two classes based on their response to mechanical stimuli. For this reason, ATP has been considered a general signal substance for tissue trauma and pain. The number and location of all nerve fibers and nerve endings vary according to the function of the tendon, being more represented in the smaller tendons involved in fine movements.
