Answer to Question #58966 in Cell Biology for tracy guido

Question #58966
Which of the following statements describes saltatory conduction? Voltage-gated sodium channels open, depolarizing unmyelinated axons Voltage-gated potassium channels open, depolarizing myelinated axons. Conduction occurs exclusively at nodes of Ranvier. Conduction occurs along unmyelinated axons, decreasing conduction velocity. What is temporal summation? addition of postsynaptic potentials due to the simultaneous stimulation of multiple synapses interaction between inhibitory postsynaptic potentials and excitatory postsynaptic potentials 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

Question 1 - correct answer Conduction occurs exclusively at nodes of Ranvier.
Action potential jumps between the nodes of Ranvier, which is specific for saltatory conduction.
Question 2 - correct answer combination of postsynaptic potentials due to the repeated stimulation of a single synapse
Repeated stimulation with stimuli below the threshold value contributes to grdual increase in depolarization rate, which finally can lead to action potential development.
