Across
  1. 3. a __________ potential is a long distance signal
  2. 5. This neurotransmitter is released at the neuromuscular junction and it is the best understood neurotransmitter
  3. 11. This phrase describes how an action potential either happens completely or does not happen at all
  4. 12. a ____________ gated ion channel opens in response to changes in membrane potential
  5. 15. An example of this is dopamine
  6. 16. The presence or absence of _________ results in two types of conduction for neurons
  7. 17. This refractory period describes the period where a neuron is not sensitive to another stimulus and will not be able have another action potential until it repolarizes some more
  8. 19. This term describes the inside of the neuron membrane becoming less negative
Down
  1. 1. This refractory period describes how a neuron is still repolarizing but if the stimulus is strong enough it can have another action potential
  2. 2. This pump maintains the membrane potential by maintaining the concentration gradients of sodium and potassium
  3. 4. play roles in emotional behaviors and the biological clock
  4. 6. neurons are highly ___________ cells
  5. 7. This term describes the inside of the neuron membrane becoming more negative than the resting potential
  6. 8. a ____________ gated ion channel opens in response to the binding of a chemical such as a neurotransmitter
  7. 9. This conduction type is faster, as the myelin acts as an insulator and keeps the current in the axons
  8. 10. a __________ potential is a short distance signal
  9. 13. the ________ membrane potential of a neuron is approximately -70mv
  10. 14. The larger the __________ of an axon, the less resistance there will be which will lead to faster impulse conduction
  11. 18. This conduction type is slower due to the absence of myelin
