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