Definitions:

Sodium Channels

Ion channels found in cell membranes that allow sodium ions to flow into or out of cells, playing a crucial role in generating and transmitting electrical signals.

Initial Segment

Area near where the axon meets the cell body that is rich in voltage-gated channels, which generate the action potential.

Voltage-Sensitive Ion Channels

Voltage-sensitive ion channels are a class of transmembrane proteins that open or close in response to changes in the electrical potential across the cellular membrane, essential for neuronal signaling.

Action Potential

An action potential is a temporary reversal in the electrical charge across a cell's plasma membrane, responsible for the propagation of nerve impulses.
