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