Bear is DePOLARizing the iceberg. He is defecting from the iceberg. His muscles are engaged, contracting and working to jump off the iceberg.


Are you having trouble remembering Depolarization and Repolarization when it comes to cardiac muscle cells? These cute polar bears will help you out.

When the electrical system if the heart stimulates a myocardial cell, dePOLARization occurs, resulting in the contraction of the stimulated heart muscle.

Cardiac cells at rest are considered polarized.

The bears have returned and are RePOLARizing the iceberg – see them RElax. The cardiac muscle is refreshed and renewed. The bears have returned to the iceberg, relaxed, refreshed, renewed, and rePOLARized

RePOLARization is the process of reaching the resting state before they can electrically simulated again.
