Repolarization Phase
A phase in the cardiac cycle where the heart muscle cells return to their resting state by repolarizing their membrane potentials.
Depolarization Phase
The process in which a cell's membrane potential becomes less negative, leading towards the threshold for an action potential.
Action Potential
A quick electrical impulse that travels down a neuron's axon, triggering the release of neurotransmitters.
Repolarization Phase
A stage in the cardiac cycle following depolarization, where the heart muscle returns to its resting state by restoring the negative charge on the cell's membrane.
