Definitions:

Potassium Channels

Protein channels in cell membranes that allow potassium ions to pass in and out of the cell, playing key roles in cell signaling and electrical conductivity.

Sodium Channels

A type of ion channel found in the membranes of cells, specifically permeable to sodium ions, crucial for initiating and conducting electrical signals in neurons.

Action Potentials

Rapid and temporary electrical impulses that travel along neurons, essential for nerve impulse transmission.

Axon Hillock

The cone-shaped region of an axon of a neuron where the axon joins the cell body, and where action potentials are initiated.
