AB The  preceding  chapter  dealt  with  pain  and  its  pathways  and  mechanisms.  There  are,  of  course,  several  other  somatosensory  experiences  that  also  utilize  specialized  end  organs,  pathways,  and  neurophysiologic  mechanisms;  these  include  touch,  vibration,  and  joint  position  senses,  appreciation  of  deep  pressure,  as  well  as  integrated  sensory  experiences  that  depend  on  cortical  functions  and  are  the  subject  of  the  current  chapter.  The  separation  between  these  two  broad  somatosensory  systems  (nociceptive,  meaning  potentially  tissue  damaging,  and  non-nociceptive)  is  logical  in  so  far  as  each  depends  on  distinctive  tracts  in  the  peripheral  nerves,  spinal  cord,  and  brain.  In  clinical  practice,  they  are  tested  to  contribute  information  regarding  the  localization  and  nature  of  a  lesion.  Because  the  peripheral  nervous  system  is  organized  in  a  segmental  pattern,  the  superficial  representation  of  somatic  sensation,  nociceptive,  and  non-nociceptive,  follows  the  dermatomal  and  peripheral  nerve  map  shown  in  Fig.  8–1.  The  special  sensory  functions  of  smell,  taste,  vision,  hearing,  and  vestibular  proprioception  are  covered  in  the  chapter  dedicated  to  those  sensory  functions.
