How to Memorize "depolarize"

1. visualize
   

   - Visualize the flow of ions across a cell membrane during depolarization, with positively charged sodium ions entering the cell and negatively charged potassium ions leaving.

2. associate
   

   - Associate the concept of depolarization with the idea of a cell losing its electrical charge, and remember that this process is crucial for the functioning of nerves and muscles.

3. mnemonics
   

   - Use the mnemonic 'Dancing Polar Bears' to remember that depolarization is the opposite of polarization.
