The action potential can cross the synaptic cleft.1 True False 2. An influx of sodium ions into the axon is what generates the action potential.1 True False 3. Saltatory conduction gets its name from the Latin word “saltare” meaning:1 jump salt fast slow synapse 4. The action potential can travel up and down, back and forth, along the neuron.1 True False 5. When the axon is resting, which is more abundant inside the membrane?1 Na Ca K 6. To what gadget do neurotransmitters stick after they cross the gap?1 potassium channels either, depending on situation sodium channels 7. What crosses the synaptic cleft?1 the action potential neurotransmitters calcium ions cytokines 8. What is the ration of Na to K ions pumped by the Na/K pump?1 100:1 6:1 3:2 1:1 9. Where does the action potential start?1 hillock Schwann cells axon terminals 10. What does the Na/K pump do?1 Maintains the resting potenial. Makes sure the action potential only goes one way. Restores the action potential. Gets rid of unwanted sodium and potassium ions. 51: Nervous tissue of the CNS 53: Muscle fibers and the neuromuscular junction Back to: 52: The action potential and the synapse
