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