Action Potentials

Quick changes in the electrical charge of a neuron's membrane, allowing the transmission of nerve impulses.

Ventricles Repolarize

The process by which the heart's ventricles return to their resting state after contraction, crucial for heart rhythm.

Pacemaker Potential

The self-generated electrical potential that triggers the spontaneous depolarization of cells in the heart's pacemaker regions, leading to heartbeat regulation.
