The action potential can travel up and down, back and forth, along the neuron.1 True False What does the Na/K pump do?1 Makes sure the action potential only goes one way. Gets rid of unwanted sodium and potassium ions. Restores the action potential. Maintains the resting potenial. When the axon is resting, which is more abundant inside the membrane?1 K Na Ca An influx of sodium ions into the axon is what generates the action potenial.1 True False To what gadget do neurotransmitters stick after they cross the gap?1 sodium channels potassium channels either, depending on situation The action potential can cross the synaptic cleft.1 True False Where does the action potential start?1 hillock axon terminals Schwann cells What crosses the synaptic cleft?1 the action potential calcium ions neurotransmitters cytokines When the axon is resting, which is more abundant inside the membrane?1 K Ca Na What is the ration of Na to K ions pumped by the Na/K pump?1 6:1 100:1 1:1 3:2 39: Erythrocytes 40: Granulocytes Back to: 52: The action potential and the synapse
