  12. ______: pick up changes in light
  13. Passing signals (information) from on neuron to another is known as: ______
  14. A unique structure found in the neuron cell body composed of clusters of rough ER (meaning they make and release proteins) are: ______
  15. Dendrites are ______which come off neurons.
  16. Dendrites ______impulses and bring them ______cell body.
  17. ______is the tail of the neuron where the signal travels ______the neuron.
  18. Axonal transport can move materials away from the cell body which is called ______transport or toward the cell body called ______transport.
  19. Two types of axonal transport are ______and ______.

Classification of Neurons

  1. Neurons may be classified by their anatomy (structure). There are 3 types:
  2. ______
  3. ______

  5. Most neurons (99%) in the CNS are ______.
  6. Neurons may also be classified by physiology (function). Two types are:
  7. ______
  8. ______
  9. ______neurons are afferent which pick up signals from the environment and deliver it to the brain.
  10. ______neurons allows information to go out (efferent) of brain to body.
  11. ______neurons are found between neurons and in the CNS only. They connect neurons together.
