52: The action potential and the synapse Quizellenj2022-11-16T23:56:13-05:00 Please sign up for the course before taking this quiz. 1. Where does the action potential start?1 Schwann cells hillock axon terminals 2. The action potential can cross the synaptic cleft.1 True False 3. Saltatory conduction gets its name from the Latin word “saltare” meaning:1 jump salt fast slow synapse 4. An influx of sodium ions into the axon is what generates the action potential.1 True False 5. The action potential can travel up and down, back and forth, along the neuron.1 True False 6. What does the Na/K pump do?1 Restores the action potential. Gets rid of unwanted sodium and potassium ions. Maintains the resting potenial. Makes sure the action potential only goes one way. 7. To what gadget do neurotransmitters stick after they cross the gap?1 potassium channels sodium channels either, depending on situation 8. When the axon is resting, which is more abundant inside the membrane?1 Na Ca K 9. What crosses the synaptic cleft?1 calcium ions the action potential cytokines neurotransmitters 10. What is the ration of Na to K ions pumped by the Na/K pump?1 1:1 100:1 6:1 3:2 51: Nervous tissue of the CNS 53: Muscle fibers and the neuromuscular junction Back to: 52: The action potential and the synapse
