In biology, depolarization or hypopolarization[1][2] is a change within a cell, during which the cell undergoes a shift in electric charge distribution, resulting in less negative charge inside the cell …

Dec 11, 2024 · Depolarization and repolarization are essential parts of the heart’s cycle, affecting muscle contraction and relaxation. In simpler terms, depolarization is when the heart cells fire off an …

Apr 30, 2024 · 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 …

Aug 5, 2025 · Depolarization is a fundamental electrical process in living organisms, involving rapid changes in the electrical charge across cell membranes. This alteration in electrical potential enables …

May 29, 2023 · 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 …

The meaning of DEPOLARIZATION is the process of depolarizing something or the state of being depolarized. How to use depolarization in a sentence.

Depolarization —a decrease in negative charge—constitutes an excitatory PSP because, if the neuron reaches the critical threshold potential, it can excite the generation of a nerve impulse (action potential).

Depolarization is a change in a cell's membrane potential, making it more positive compared to its resting state. This process is crucial for the generation of action potentials in excitable cells, such as …

Mar 6, 2024 · 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. This change in charge …

4 days ago · In this article, we’ll dive into the key differences between depolarization and repolarization and how these electrical processes are vital for maintaining a healthy and functioning heart.
