Definitions:

Activation Gate

In the context of cell membrane channels, this refers to a mechanism that opens or closes ion channels in the cell membrane in response to physiological stimuli.

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.
