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