    The 3 types of neurons are,
    • A. 

      Sensory (Afferent) Neurons, Glial Neurons, Parasympathetic Neurons

    • B. 

      Sensory (Afferent), Interneurons, Motor (Efferent)

    • C. 

      Sensory (Efferent), Interneurons, Motor (Afferent)

  • 3. 
    The spaces between Schwann Cells are called,
    • A. 

      Axons

    • B. 

      Synapsis

    • C. 

      Neurilemma

    • D. 

      Nodes of Ranvier

  • 4. 
    Describe the reflex arc
    • A. 

      Sensory Neurons > Interneurons > Receptors On Skin > Motor Neurons > Effectors > Reaction

    • B. 

      Reaction > Interneurons > Receptors On Skin > Motor Neurons > Effectors > Sensory Neurons

    • C. 

      Receptors On Skin > Sensory Neurons > Interneurons > Motor Neurons > Effectors > Reaction

    • D.

  • 5. 
    Grey matter is found in the [blank] and are [blank]
  • 6. 
    White matter is found in the [blank] and are [blank]
  • 7. 
    During resting potental, the charge inside the cell is [blank] whereas the charge outside of the cell is [blank]
  • 8. 
    Action Potentional works like this,
    • A. 

      1. Na+ ions rush into the neuron through the open Na+ channels 2. Na+ ions difuse to the insdie of the neuron 3. Build up of Na+ inside neuron occur, causing Na+ channels to close 4. K+ Channels open, allowing K+ ions to diffuse out of the neuron 5. Na+/K+ pump restores resting potention of neuron's member

    • B. 

      1. K+ ions rush into the neuron through the open K+ channels 2. K+ ions difuse to the insdie of the neuron 3. Build up of K+ inside neuron occur, causing K+ channels to close 4.

    Neurotransmitters that open Na+ channels and depolarize the membrane initiating an action potential are called [blank] stimulations.
    • A. 

      Inhibitory
