depolarized

Meanings

• verb (transitive)

  The process by which an excitable cell or tissue, such as a neuron or muscle fiber, loses its electrical charge, making it less likely to generate an action potential.

  - "The heart muscle cells undergo depolarization before contracting."
  - "During an electroencephalogram (EEG), the brain's electrical activity is recorded by detecting the depolarization and repolarization of neurons."

How to Memorize "depolarized"

1. visualize
   

   - Visualize the process of an action potential: depolarization leads to a brief opening of ion channels, allowing the influx of positively charged ions and the generation of an action potential.

2. associate
   

   - Associate depolarization with the loss of electrical charge in a cell or tissue.

3. mnemonics
   

   - Use the mnemonic 'Dear Oh Polly' to remember the order of events in the cardiac cycle: Depolarization, Excitation, Repolarization, and Resting.
