Across
  1. 2. Branched extensions of a neuron that receive signals from other cells.
  2. 7. The long process of a neuron that carries electrical impulses away from the cell body.
  3. 8. The part of the neuron that contains the nucleus and controls cell functions.
  4. 9. A fatty layer that insulates axons and speeds up nerve impulse transmission.
  5. 10. A gap in the myelin sheath where the axon is exposed; helps speed up nerve impulses.
  6. 11. A cell in the PNS that creates the myelin sheath around axons.
  7. 13. An electrical signal that travels along a neuron.
  8. 14. A type of neuron with a single process extending from the cell body.
Down
  1. 1. A cell that transmits electrical signals in the nervous system.
  2. 3. A cluster of neuron cell bodies in the PNS.
  3. 4. An extension from the cell body of a neuron (e.g., axon or dendrite.
  4. 5. The end of an axon where neurotransmitters are released to communicate with other neurons.7. **Synaptic Knob**: The small bulb at the end of an axon terminal that releases neurotransmitters.
  5. 6. A type of neuron with multiple dendrites and one axon.
  6. 12. A type of neuron with two processes, one dendrite and one axon.
