When a neuron is stimulated,tiny protein structures on the cell membrane are activated and pump specific ions back and forth,thus changing the overall potential of the neuron.These cell membranes are called___________:

Question

Quizplus · Accepted Answer

Ion channels are protein structures on the cell membrane that regulate the movement of ions such as sodium, potassium, and calcium in and out of the neuron. When a neuron is stimulated, these ion channels open and allow ions to move, which changes the overall potential of the neuron and generates an action potential.
