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