Acetylcholine in the synaptic cleft binds toMultiple ChoiceLigand-gated sodium channelsCarrier proteinsSynaptic vesiclesCalcium ions

Acetylcholine is released into the synaptic cleft under the influence ofMultiple ChoiceCalcium ionsLocal currentsSodium ionsLow concentration of choline

Acetylcholine is released into the synaptic cleft under the influence of

Synaptic vesicles of somatic neurons contain Multiple ChoiceAcetylcholinePredominately calcium ionsStored cholinePredominately sodium ions

As a result of calcium ions diffusing into the presynaptic cell,Multiple Choiceacetylcholine is actively transported to the postsynaptic neuron.synaptic vessels migrate to the plasma membrane and release acetylcholine.sodium ions diffuse into the cell.acetylcholine is actively transported from the presynaptic neuron.ligand-gated sodium channels open.

Synaptic potentials are due to the opening of what type of channels?Multiple ChoiceVoltage-gated ion channelsChemically-gated ion channels
