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