Nerves Have Axons, Dendrites and Cell Bodies

  • Nerve cells are designed to respond to stimuli and transmit information over long distances
  • Nerve cell has 3 parts:
    • Cell body:
      • Has single nucleus
      • Has most of nerve cell metabolism, especially protein synthesis
      • Proteins made in cell body must be delivered to other parts of nerve
    • Axon:
      • Long cylinder, designed to transmit an electrical impulse
      • Can be several meters long in vertebrates (giraffe axons go from head to tip of spine)
      • Has axonal transport system for delivering proteins to ends of cell
