Receptor molecules that are particularly important for the function of muscle nociceptors are acid-sensing ion channels (ASICs) that open at a low tissue pH, P2X3 receptors that are activated by binding adenosine triphosphate (ATP), and the transient receptor potential receptor subtype 1 (TRPV1) that is sensitive to high temperatures and low pH.In skeletal muscle, the free nerve endings appear to be distributed quite evenly. Baroreceptors. Several classes of nociceptors have been described. Nociceptors are free (bare) nerve endings found in the skin (Figure 6.2), muscle, joints .
