  8. Which of the following is NOT part of the central nervous system? • spinal cord • cerebrum • cranial nerves • brain

  9. Which part of the brain acts as a relay station, sending sensory nerve impulses like pain and touch from the body to the cerebrum? • brainstem • thalamus • hypothalamus • pons

  10. What is the word for the multiple branches found at the beginning of a neuron that receive neurotransmitters from the previous neuron? • myelin sheaths • Synapses • dendrites • axons
