1. Nociceptors differ from other nerve receptors in the body in that they: a. adapt very little to continual pain response. b. inhibit the infiltration of neutrophils and eosinophils. c. play no role in the inflammatory response. d. transmit only the thermal stimuli. ANS: A Nociceptors are stimulated by mechanical, chemical, or thermal stimuli. Nociceptors differ from other nerve receptors in the body in that they adapt very little to the pain response. The body continues to experience pain until the stimulus is discontinued or therapy is initiated. This is a protective mechanism so the body tissues being damaged will be removed from harm. Nociceptors usually initiate inflammatory responses near injured capillaries. As such, the response promotes infiltration of injured tissues with neutrophils and eosinophils.
