Polarization Static

_Static polarization_ is one of the metabolic processes that occurs in biomolecules and consists of establishing charges inside cells, which is achieved by equalizing the potential or kinetic functions of plasma particles inside electrolytic liquids. This process is named after the English physicist James Priestley, who first proposed the concept and studied its functioning and significance for living organisms.

_Polarization of excitable tissues_ is a process of membrane electrogenesis, during which a redistribution of nonequilibrium local charges of diffusion origin occurs, providing an increase in potential. It is characterized by a change in the potential and the potential difference index on the membrane during excitation. In the resting state, local charges have unequal values, depending on the ionic strength of the medium. When a potential acts on the tissue, a slowly decaying wave of local potentials arises and suppresses. The sum of surface negative values ​​of local potentials on the surface of biological tissue is called _potential difference._ The greater the difference in the value of the redox potential of ions on both sides of the membrane of an excitable object (when compared with equilibrium values), the higher the ion asymmetry. In general, all this greatly affects the functioning of cells, since the permeability of selectively impermeable biological membranes depends on the presence and degree of their polarization.

**Polarization** is the process of changing the cell membrane potential or tissue excitability when exposed to excitation. This process plays an important role in the regulation of biological processes and interactions between cells.

**Static polarization** is one of the types of polarization in which the potential difference between the inner and outer sides of the membrane remains unchanged. Static polarization occurs in excitable tissues such as nerve cells and muscle fibers, where the resting potential does not change, but an action potential appears.

One example of such polarization can be found in the activity of the heart muscle. At rest, the heart muscle is polarized
