      Through contact between the dendrites of one neuron and the axon branches of the next

    • B. 

      Through neurotransmitting chemicals that float between the synapse space

    • C. 

      Through electrochemical signals that pass from axon to axon

    • D. 

      By an electrical current that is transmitted from the dendrite of the first neuron to the axon branch of the second neuron

  • 4. 
    All actions that occur as a result of the nervous system are controlled by the brain
    • A. 

      True

    • B. 

      False

  • 5. 
    Sensory neurons carry impulses through the nervous system...
    • A. 

      From the brain

    • B. 

      To the brain

  • 6. 
    The peripheral nervous system...
    • A. 

      Branches off the brain and spinal cord and is responsible for muscle movement.

    • B. 

      Is connected to the central nervous system and is responsible for gathering sensory information.

    • C. 

      Responsible for collecting and acting on information that is interpreted by the brain.

    • D. 

      Connects the central nervous system to the environment to gather sensory input and create motor output.

  • 7.

    • A. 

      Action, sensory neuron, inter-neuron relay, motor neuron, stimulus

    • B. 

      Stimulus, sensory neuron, spinal cord to brain interaction, motor neuron, effector (action)

    • C. 

      Stimulus, sensory neuron, inter-neuron relay, motor neuron, effector (action)

    • D. 

      Action, brain to spinal cord interaction, motor neuron, muscle movement

  • 8.

    • B. 

      Electrical impulse passed out of CNS and carried to the PNS through motor neurons

    • C. 

      Sensory information carried via sensory neurons through the PNS to the CNS

    • D. 

      Sensory information reaches the CNS inter-neuron relay

    • A. 

      Sensory information is passed through the afferent pathway to the control centre where it is interpreted

    • B. 

      Nerve impulse are sent from the control centre along the afferent pathway to the muscles
