Across
  1. 5. Specialized cells transmitting nerve impulses.
  2. 8. Neurons taking information from the brain to the rest of the body.
  3. 9. Cell bodied containing the nucleus and other parts of the cell needed to sustain its life.
  4. 11. Wirelike structure ending in the terminal buttons that extends from the cell body.
  5. 12. Proteins recognizing and bonding to specific molecules.
  6. 15. Neurotransmitters exciting the next cell into firing.
  7. 16. Neurotransmitters inhibiting the next cell from firing.
  8. 17. Neurons taking the messages and sending them elsewhere in the brain or on to efferent neurons.
  9. 18. The space between the terminal buttons of one neuron and the dendrites of the next neuron.
Down
  1. 1. A rapid sequence of changes in the voltage across a membrane.
  2. 2. Chemicals contained in terminal buttons that enable neurons to communicate.
  3. 3. The branched end of the axon that contain neurotransmitters.
  4. 4. A fatty covering around the axon of some neurons that speeds neural impulses.
  5. 6. Rootlike parts of the cell that stretch out from the cell body.
  6. 7. The cylindrical bundle of nerve fibres and associated tissue which is inclosed in the spin and connects nearly all parts of the body to the brain.
  7. 10. Neurons taking information from the senses to the brain.
  8. 13. Certain reactions occurring the moment sensory impulses reach the spinal cord.
  9. 14. An organ of soft nervous tissue contained in the skull of vertebrates.
