In response to an action potential, voltage-gated calcium channels Blank______ in the presynaptic cell's axon terminal.Multiple choice question.closeopen

Each action potential Blank______.Multiple choice question.begins in the synaptic terminal and spreads up the axon to the axon hillockspreads across the entire surface of the membrane so that the entire cell is depolarized at one timeaffects only a small area of the plasma membrane of the cell at a timebuilds upon the previous action potential to create a larger potential change

When traveling along an axon, the cell membrane immediately ahead of an action potential depolarizes because of _________blank.Multiple Choicethe sodium/potassium pumpmembrane receptorsdiffusion of sodium currentdecreased membrane permeabilitypotassium efflux

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.

Synaptic potentials are __________Blank potentials resulting from opening or closing __________Blank-gated ion channels.Multiple Choicelocal; chemicallyaction; voltageaction; chemically

Each presynaptic terminal contains _________blank, which contain the neurotransmitter _________blank that, when released, cause ligand-gated Na+ channels to open in the motor end-plate. This causes _________blank in the muscle cell.Multiple Choicesynaptic vesicles; acetylcholine; depolarizationproteins; acetylcholine; repolarizationmitochondria; acetylcholinesterase; depolarizationACh receptors; acetylcholinesterase; repolarization
