Sentences with phrase «charged sodium ions»

When nerve cells receive a signal of pain or other sensation, the signal opens sodium channels and floods the cell with positively charged sodium ions, which positively charge the neurons until the electrochemistry changes enough to inactivate the channels and close them.
In this scenario, when an object moved in the neuron's preferred direction, excitatory impulses would reach the target neuron first, triggering positively charged sodium ions to flow into the cell — an excitatory current.
Most of these so - called «pacemaking neurons» utilize charged sodium ions to create their electrical impulses.

Bound to the cell membrane, Na ± K+ATP ase uses the energy of adenosine triphosphate (ATP) molecules to pump sodium out of the cell and potassium into the cell, maintaining a charge gradient that allows ions to flow through open channels.
When the neuron is stimulated, sodium ions rush into the cell and potassium ions rush out, leaving the neuron with a positive electrochemical charge.

Charge - holding capacity was only marginally reduced for the saline - and cell - culture - based batteries, most likely because they had slightly lower sodium - ion content than the sodium sulfate solution.
The mechanism is produced by layers of electrically charged particles (ions of sodium and potassium) on either side of the nerve membrane that change places when stimulated.
Researchers have known for decades that some microorganisms, such as single - celled green algae, have proteins that respond to light by opening a channel in the microbe's membranes, allowing the passage of electrically charged ions (such as calcium and sodium).
(An example of this is table salt, made up of positively charged sodium and negatively charged chlorine ions).
