Depolarization is initiated by a stimulus that makes the membrane potentialMultiple ChoiceNeutralMore negativeMore positiveUnchanged

When a neuron is depolarized, the inside of the membrane temporarily becomes  amore negative than the outside bmore positive than the outside cneutral compared to the outside dNone of the above

A depolarization that happens in a sensory receptor on stimulation is known as a potential.

Depolarization of a cell membrane occurs becauseMultiple ChoiceSodium ions are blocked from entering the cellMore sodium ions diffuse into the cell than potassium ions diffuse out of itThe concentration of sodium and potassium ions in the extracellular fluid is at equilibriumThe concentration of sodium and potassium ions in the cell is at equilibrium

What is produced when depolarization of a cell membrane reaches threshold?Multiple ChoiceA new action potential is produced.Membrane receptors are exposed.The absolute refractory period ends.An existing action potential is stopped.

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
