True or false?
During saltatory conduction, action potentials are regenerated at sites called gap junctions.
TRUE OR FALSE?
Do translatory conduction involves the entire length of the axon in the propagation of the action potentials?
True/False - The action potential is always the same size, regardless of the strength of excitatory signaling that a neuron is receiving.

- 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.arrow_forwardrearrange these in the correct order of events in an action potential.arrow_forwardpotential across a synapse is regulated). produce an effect by targeting a different part of the process by which conduction of an actionarrow_forward
