What are facts about muscle cells?
They behave like tiny batteries, with voltages (known as membrane potentials) in the millivolt range. This property enables the cells to generate tiny electrical currents, making it possible for the muscle cells to "twitch", i.e., contract and to pump blood (heart muscle). Normally, heart muscle cells in the adult no longer divide. They can only increase in size.
