Terms to Know
Action Potential

The state in which a neuron reaches its Threshold of Excitation and fires, or sends an electrical impulse down the axon.

Ion Channels

Small tunnels along a neuron that to pump ions from one side of the cellular membrane to the other, which creates an electrical charge.

Resting Potential

The state in which a neuron is not firing or sending a neural impulse and when there is a negative electrical charge inside the neuron.

Threshold of Excitation

The level or point at which a neuron fires, or a neural impulse is triggered.
