Answer on Cell Biology Question for Tracy Guido
Which of the following statements describes saltatory conduction?
Conduction occurs exclusively at nodes of Ranvier.
Voltage-gated sodium channels open, depolarizing unmyelinated axons.
Voltage-gated potassium channels open, depolarizing myelinated axons
Conduction occurs along unmyelinated axons, decreasing conduction velocity.

combination of postsynaptic potentials due to the repeated stimulation of a single synapse
predisposition for a neuron to be excited due to previous stimuli shifting the baseline potential towards threshold
addition of postsynaptic potentials due to the simultaneous stimulation of multiple synapses
interaction between inhibitory postsynaptic potentials and excitatory postsynaptic potentials
28. addition of postsynaptic potentials due to the simultaneous stimulation of multiple synapses
