What effect does acetylcholine have on the postsynaptic neuron?Multiple ChoiceTerminal vessels migrate to the plasma membrane.Ligand-gated sodium ion channels open and sodium diffuses in.Voltage-gated sodium ion channels open and sodium diffuses in.Ligand-gated calcium ion channels open and calcium diffuses in.Voltage-gated calcium ion channels open and calcium diffuses in.

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.

An action potential arriving at the presynaptic terminal causesMultiple Choicevoltage-gated sodium ion channels to open, and sodium ions to diffuse out of the cell.voltage-gated calcium ion channels to open, and calcium ions to diffuse into the cell.voltage-gated sodium ion channels to open, and sodium ions to diffuse into the cell.ligand-gated sodium channels to open, and sodium ions to diffuse out of the cell.acetylcholine to diffuse into the cell.

What effect will a neurotransmitter have on the postsynaptic membrane?Multiple choice question.It will always produce a hyperpolarization.It will always produce a depolarization.It may produce a depolarization or a hyperpolarization.

Action potentials arriving at a presynaptic terminal causeMultiple Choicebreakdown of acetylcholine.calcium ion channels to close.release of neurotransmitter.calcium ion channels to open.

Chemical synapses in the nervous system a- allow diffusion of chemical substances form the presynaptic neuron into the postsynaptic neuronb- allow transmission of potential changes in one direction only; from the presynaptic to the postsynaptic neuronsc- have potential-gated ionic channelsd- are more numerous in the peripheral nervous system than the central nervous system
