Depolarization - Wikipedia
网页Depolarization is the process by which the membrane potential becomes less negative, facilitating the generation of an action potential. [6] . For this rapid change to take place within the interior of the cell, several events must occur along the plasma membrane of …

Depolarization: Definition, Mechanism, vs. Repolarization
网页2024年4月30日 · Depolarization is the cellular event characterized by the shift in the distribution of electric charges within a cell, particularly evident in cell membranes, majorly neural membranes for the conduction of impulses.
Depolarization Definition & Meaning - Merriam-Webster
网页1. : the process of depolarizing something or the state of being depolarized. 2. physiology : loss of the difference in charge between the inside and outside of the plasma membrane of a muscle or nerve cell due to a change in permeability and migration of …

Depolarization - Biology Simple
网页2024年3月6日 · Depolarization is the process of a neuron’s membrane potential becoming less negative. Depolarization occurs when the neuron receives a stimulus, causing positive ions to enter the cell and shifting the electrical charge towards a more positive state.
Depolarization (Definition + Process) - Practical Psychology
网页2022年7月6日 · Depolarization is a shift in a cell's electric charge that makes the cell's interior increasingly more positive than the exterior. Electrical stimuli, or excitatory stimuli that raise the cell's voltage, cause the voltage-gated ion channels to open in the cell.
Depolarization - Definition and Examples - Biology Online
网页2023年5月29日 · Depolarization is when a change occurs inside a cell that causes the distribution of electric charges to alter, leaving the cell with a less negative charge than the outside. Numerous cell functions, cell-cell communication, and the general physiology of an organism all depend on depolarization.
Depolarization | bioelectricity | Britannica
网页In nervous system: Depolarization. Because it varies in amplitude, the local potential is said to be graded. The greater the influx of positive charge—and, consequently, depolarization of the membrane—the higher the grade. Beginning at the resting potential of a neuron (for instance, −75 mV), a local potential can… Read More.
Depolarization - definition - @neurochallenged
网页Depolarization - movement of a cell's membrane potential to a more positive value (i.e. movement closer to zero from resting membrane potential). When a neuron is depolarized, it is more likely to fire an action potential.
