When a neuron is stimulated, tiny protein structures embedded in the cell membrane are activated and allow specific ions to cross the cell membrane, thus changing the overall potential of the neuron. These tiny protein structures are called _____________.
A)ion channels
B)action potentials
C)neurotransmitters
D)glial cells
