Across
- 3. Type of neuron that conducts signals from receptors to the central nervous system
- 5. Certain level of membrane potential to be surpassed
- 6. Neurotransmitter that transmits signals to skeletal muscles
- 7. "Downtime" after an action potential when a second action potential cannot be initiated
- 8. Neuronal process that transmits the action potential
- 9. Sodium channels close and potassium channels open causing this
- 12. Lipid that insulates the axon
- 14. Another word for the cell body of a neuron
- 16. Constant voltage across neuron membranes
- 17. Sodium ions flood in across the membrane causing this
- 18. Protein that helps re-establish the resting potential
Down
- 1. Electrical signal that travels along the axon
- 2. Chemical that moves across a synapse
- 4. Neuronal processes arising from the nerve cell body that receive input
- 10. Muscles or glands can be these
- 11. Junction between a neuron and its target cell for transmission of information
- 13. The membrane potential has briefly fallen below -70mV
- 15. Type of cell that makes up the myelin sheath
