Structure and function of neurons

Cards (3)

  • What are the 3 types of neurons
    • Sensory
    • Relay
    • Motor
  • Describe the structure of a neuron:
    • Cell body contains nucleus and has dendrites
    • Axon covered in myelin - a sheath divided by nodes of Ranvier
  • Describe electrical transmission:
    When a neuron is activated by a stimulus, the inside becomes positively charged for a split second causing an action potential to occur. This creates an electrical impulse that travels down the axon towards the end of the neuron
