Acetylcholine is released into the synaptic cleft under the influence ofMultiple ChoiceLocal currentsLow concentration of cholineSodium ionsCalcium ions

Synaptic vesicles of somatic neurons contain

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.

Increased calcium ion permeability of the presynaptic terminal cell membrane is caused by an ______________.Multiple Choiceacetylcholinesodium ionsaction potentialincreased concentration of calcium ions
