NERVOUS SYSTEM III Flashcards

1
Q
  • Involuntary reaction to a stimulus applied to the periphery and
    transmitted to the CNS
  • Saves us from dangerous stimuli
  • Fast, automatic, involuntary
  • Occurs without our conscious thinking
  • Mostly associated with pain
  • Information detected by sensory receptors will be integrated to either spinal cord or lower center of the brain
