1
Q

what is the function of the nervous system?

A
  • allows us to experience the world through senses and react to them appropriately via a complex network of nerve cells that regulates responses to internal and external stimuli

Q

how is the nervous system categorised?

A
  • anatomical - central (CNS)- brain and spinal chord & peripheral (PNS)- everything else
  • physiological - somatic- voluntary control (PNS)
    visceral - involuntary control (CNS & PNS)

Q

Q

cell bodies in CNS vs PNS

A
  • CNS- found in collections within grey matter
