Definitions:

Transport Pump

Proteins in cell membranes that use energy to move substances across the membrane, often against a concentration gradient.

Saltatory Conduction

The transmission of a neural impulse along a myelinated neuron; ion activity at one node depolarizes the next node along the axon.

Voltage-Activated

Pertains to ion channels in cell membranes that open or close in response to changes in membrane potential.

Action Potential

A rapid rise and subsequent fall in voltage or membrane potential across a cellular membrane, due to the movement of ions in and out of the neuron.
