What to Focus On

  • Coordination is the linking of body activities according to body needs.
  • Nervous coordination is controlled by the nervous system.
  • Chemical coordination is controlled by hormones.
  • A neuron has two main parts: cyton and axon.
  • The cyton contains the nucleus.
  • Dendrites are extensions of the cell body.
  • A nerve is a bundle of axons.
  • The medullary sheath acts as insulation.
  • Sensory nerves carry only sensory neurons.

Common Mistakes to Avoid
