Neurons

• Sensory Neurone


  Detects sensations at receptors, releasing action potential to travel the myelinated axon, converting to a chemical signal at the synapse

  • Structure: Receptor, Myelin sheath, Axon, Cell body, Synapse
• Relay Neurone


  After synaptic transmission, new action potential is formed, sending signal to CNS and along axon to motor neurone

  • Structure: Dendrites, cell body, axon, pre-synaptic terminal
• Motor Neurone


  Detects signal from relay neurone via synaptic transmission, passes action potential down myelinated axon to stimulate the effector

  • Structure: Dendrites, cell body, myelin sheath, axon, neurofibril node, effector
