neuron types

• sensory 


  -carry nerve impulses from sensory receptors to spinal cord & brain

  -covert info from sensory receptors into neural impulses

  -translated to sensations at brain
• what happens to some of the sensory information?

  -only travels to spinal cord

  -allow for reflex reactions (much quicker)
• relay neurons

  -allow sensory & motor neurons to communicate

  -found wholly within brain & spinal cord

  -interneurons
• motor neurons

  -located in CNS

  -send messages from brain to muscles

  -directly or indirectly control muscles by forming synapses

  -release neurotransmitters when stimulated
• neurotransmitters

  -bind to receptors on muscles

  -trigger response
