Verywell Health articles are reviewed by board-certified physicians and healthcare professionals. Nociceptors, although polymodal, can be further divided into two main classes on the basis of response to mechanical stimuli, leading to a distinction between mechanically sensitive afferents (MSA) and mechanically insensitive afferents (MIA) defined as afferents that have very high mechanical thresholds or are unresponsive to mechanical stimuli. 2005; 320:201-206, Ashton IK, Ashton BA, Gibson SJ, Polak JM,Jaffray DC,Eisenstein SM.
