  1. 7. Branching structures that let the neuron reach out to gather stimuli from other cells or from the environment.
  2. 9. As potassium ions flow out of the membrane after depolarization, the negative-inside, positive-outside state of he cell is restored, which we call...
  3. 10. This part of the neuron is responsible for keeping the neuron alive.
  4. 14. Considered the conductor of the neuron. Action potentials travel down the membrane of this structure.
  5. 15. Cells specialized to transmit electrical signals.
  6. 16. Convert the electricity of the nerve impulse into a chemical signal.
Down
  1. 1. The space between two neurons at the synapse.
  2. 2. The junction a nerve impulse is passed from one cell to another.
  3. 3. Insulates the axon, making the action potential move down more quickly. This covering also protects the axon.
  4. 4. The type of transport used by the sodium-potassium pump to move sodium ions out of the cell and potassium ions back into the cell.
  5. 5. When neurotransmitters bind to these proteins, the proteins change shape which opens ion channels.
  6. 6. This type of neuron carries signals from the brain or spinal cord to your muscles, organs, and glands.
  7. 7. The shift in charge inside the cell membrane when sodium ions rush in.
  8. 8. This type of neuron connects other neurons to create pathways through the body or brain.
  9. 11. Where the neuron's DNA is contained.
  10. 12. Branching structures at the end of the axon which contain neurotransmitters.
  11. 13. This type of neuron responds to stimuli and sends information to either the brain or spinal cord.
