An excitatory message causes:
A)channels to open in the neuron's membrane that allow chloride ions to flow out
B)channels to open in the neuron's membrane that allow sodium ions to flow in
C)channels to open in the neuron's membrane that allow potassium ions to flow in
D)the neuron's sodium/potassium pump to be inactivated

Question

Quizplus · Accepted Answer

An excitatory message causes channels to open in the neuron's membrane that allow sodium ions to flow in. This influx of positive ions depolarizes the neuron and can lead to the generation of an action potential.
