| Comments | Muscle cells in which such depolarization leads to muscle contraction often have a diameter of about 50 µm, and a simple estimate (see Phillips et al., “Physical Biology of the Cell”, Chapter 17) reveals that the change in the internal charge within the cell as a result of membrane depolarization is only about a thousandth of a percent (10^-5) of the charge within the cell. |
