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