Sodium Channel
Sodium channels are integral membrane proteins that form ion channels, conducting sodium ions (Na+) through a cell's plasma membrane. They are classified according to the trigger that opens the channel for such ions, i.e. either a voltage-change ("Voltage gated", "voltage sensitive" or "voltage dependant" sodium channel also called "VGSCs" or "Nav channel") or binding of a substance (a ligand) to the channel (ligand-gated sodium channels).
In excitable cells such as neurons, myocytes, and certain types of glia, sodium channels are responsible for the rising phase of action potentials.

Famous quotes containing the words sodium and/or channel:
“Every reader of the Dreiser novels must cherish astounding specimens—of awkward, platitudinous marginalia, of whole scenes spoiled by bad writing, of phrases as brackish as so many lumps of sodium hyposulphite.”
—H.L. (Henry Lewis)
“This is what the Church is said to want, not party men, but sensible, temperate, sober, well-judging persons, to guide it through the channel of no-meaning, between the Scylla and Charybdis of Aye and no.”
