Peripheral nervous system

  • The peripheral nervous system (PNS) is all the nervous tissue outside the central nervous system (CNS)
  • It is divided into the somatic nervous system and autonomic nervous system and is made of 43 pairs of nerves:
    • 12 pairs of cranial nerves
    • 31 pairs of spinal nerves
  • Function: the somatic nervous system receives information from receptors and conveys the information to the CNS
  • It also transmits the impulses from the CNS to effector organs.
