If a neurotransmitter causes ligand-gated sodium channels to open, what occurs to the membrane?Multiple choice question.HyperpolarizationDepolarization

Hyperpolarization occurs because voltage-gated Blank______ channels stay open longer than required to reach resting membrane potential. Multiple choice question.sodiumpotassium

What will trigger the opening of chemically gated ion channels?Multiple choice question.binding of neurotransmitter moleculeschanges in membrane potential

Opening of sodium channels in the axon membrane causes: Question 26Select one:a.depolarization.b.repolarization.c.hyperpolarization.d.increased negative charge inside the membrane.e.inhibition.

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.

Which event occurs during neuronal depolarization? a. membrane potential returns to normal b. cations leave the cytosol c. membrane potential remains stable d. membrane potential decreases e. plasma membrane becomes less permeable
