What do sensory neurons do and where are they found?

  • carry nerve impulses to brain where they are translated into ‘sensations’ (vision, hearing, taste, touch)

  • Some sensory neurons stop at spinal cord, allowing for quick reflex actions

  • Found in receptors (skin, eyes, ears, tongue)

What do relay neurons do and where are they found?

  • allow sensory + motor neurons to communicate

  • Found in brain and spinal cord

What do motor neurons do and where are they found?

  • control muscle movements

  • When stimulated, release neurotransmitters that bind to the receptors on muscles to trigger a response, leading to movement

  • Found in CNS
