- What is the difference between an action potential and a synapse? (select all that apply) The action potential moves down the axon and a synapse is between neurons. The synapse travels long distances and the action potential can only travel short distances. The action potential starts at the dendrites and the synapse starts at the ахon. The action potential is always the same and the synaptic potentials vary. the action potential involves only the postsynaptic neuron, but the synapse involves both the pre- and post-synaptic neurons.An Intact Neuron and Voltmeter Select one: +H -0,+ V the neuron is resting + + ++ The voltage polarity is positive when + + + + + + the neuron has a high concentration of K+ ions an action potential dies out before reaching the axon an action potential is being transmittednswer After an action potential is generated in a neuron, it travels to the end of the axon. Explain how the absolute refractory period prevents the action potential from travelling back to the cell body, and why it does not prevent the action potential from moving down to the end of the axon.
