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