AB ObjectivesAfter  studying  this  chapter,  the  student  should  be  able  to:Understand  how  the  skin  elaborates  a  variety  of  receptors  that  sense  various  kinds  of  touch,  temperature,  and  pain.See  how  receptors  for  various  skin  sensations  have  different  anatomic  morphologies  and  physiologic  transduction  mechanisms.See  the  relationship  between  different  mechanoreceptor  types  and  the  ensuing  perceptions,  such  as  vibration  or  pressure,  associated  with  stimulation  of  that  receptor  type.Understand  how  the  spatial  resolution  of  touch  is  related  to  the  density  of  receptors  in  any  skin  area  and  inversely  related  to  receptive  field  (RF)  size.Follow  the  pathway  for  transmitting  touch,  temperature,  and  pain  perception  from  sensory  neurons  in  the  dorsal  root  ganglia  of  the  spinal  cord,  up  through  spinal  cord  pathways  to  the  brainstem  and  thalamus,  and  then  to  somatosensory  cortex  in  the  most  anterior  portion  of  the  parietal  lobe.See  how  transient  receptor  potential  (TRP)  channels  mediate  temperature  sensation.Understand  psychological  aspects  of  pain  perception  and  the  role  of  endorphins.Learn  what  regions  of  the  brain  process  somatosensory  information.See  how  proprioception  and  kinesthesis  (joint  position,  movement,  and  force)  are  mediated  by  receptors  similar  to  mechanoreceptors.
