52: The action potential and the synapse Quizellenjmchenry2019-06-14T00:27:52-04:00 Please sign up for the course before taking this quiz. 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. When the axon is resting, which is more abundant inside the membrane?1 Na Ca K To what gadget do neurotransmitters stick after they cross the gap?1 sodium channels potassium channels either, depending on situation What is the ration of Na to K ions pumped by the Na/K pump?1 100:1 3:2 1:1 6:1 The action potential can travel up and down, back and forth, along the neuron.1 True False Where does the action potential start?1 Schwann cells axon terminals hillock The action potential can cross the synaptic cleft.1 True False What crosses the synaptic cleft?1 calcium ions cytokines neurotransmitters the action potential An influx of sodium ions into the axon is what generates the action potenial.1 True False When the axon is resting, which is more abundant inside the membrane?1 Ca K Na 51: Nervous tissue of the CNS 53: Muscle fibers and the neuromuscular junction Back to: 52: The action potential and the synapse
