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