Membrane Potential Sign Video

No video uploaded yet.

Definition

The voltage recorded across a plasma membrane due to an unequal distribution of ions and charged molecules on either side of the membrane. Such an unequal distribution of charge is caused by selective permeability of plasma membranes to specific ions and charged molecules.
