Question

Quizplus · Accepted Answer

In its resting state, a neuron is said to be polarized. This means that there is an electrical charge difference or potential difference between the inside and outside of the neuron. The inside is mostly negatively charged due to the presence of anions such as proteins and organic molecules, while the outside is mostly positively charged due to the presence of cations such as sodium and potassium ions. This polarization is maintained by the selective permeability of the cell membrane and the activity of ion channels and pumps.
