Definitions:

Resting Membrane Potential

The electrical charge difference across the cell membrane when the cell is in a non-excited state.

Local Potential

A temporary, localized change in resting potential, usually occurring in neurons, that can lead to an action potential if it reaches threshold.

Electrically Excitable Cells

Cells that can change their membrane potential in response to a stimulus, leading to generation and propagation of action potentials.

Depolarization

A reduction in the difference in electrical charge across a cell's plasma membrane, which is a crucial step in the conduction of impulses along nerve cells.
