  • When the skin is image descriptionpenetrated by a sharp object such as a tack, the resulting damage is detected by pain receptors (or nociceptors).
  • Electrochemical impulses (or actions potentials) are generated in somatic sensory neurons and image descriptionconducted into the CNS.
  • Another set of neurons image descriptioncarry the information up the central nervous system to the cerebral cortex, where the pain is imaged and interpreted.

  • After stimuli (such as pain) are processed in the brain, other neurons plan adjustment responses (to remove the tack).
  • Implementation of a (pain) response begins when CNS neurons image descriptionconduct impulses from the cerebral cortex to the spinal cord.
  • In the spinal cord, the impulses are image descriptiontransmitted to somatic motor neurons, which carry them out to the skeletal muscles (needed to remove the tack).
