Ascending Somatosensory Systems

  • William D. WillisJr.


The ascending somatosensory pathways signal to the brain information concerning stimuli that are applied to the body or head. This chapter considers only those pathways that convey sensory information from the body. The term “somatosensory” is somewhat misleading, since the somatosensory pathways are used for the perception of signals originating from the viscera (see Foreman, Chapter 10) in addition to those coming from sensory receptors located in such somatic structures as the skin, muscles, and joints. Thus, the pathways to be discussed mediate both somatic and visceral sensation.
