Sentences with phrase «sodium ions flow»

The SCN5A protein winds through the membrane of heart muscle cells, forming a channel that opens to let sodium ions flow into the cells.

When appropriately stimulated, the channels open, sodium ions flow in, and the muscle cells contract.

Drugs that specifically target the persistent sodium ion flow, or current, have been approved by the Food and Drug Administration for treating epilepsy.

Not exact matches

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 you stimulate a neuron, ions like sodium and potassium and chloride flow back and forth, causing what's called an action potential to travel down the neuron, through the axon, to a synapse.

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.

According to a research team led by Thomas Hund, the key may reside in voltage-gated sodium channels, nanoscopic pores that control the flow of sodium ions across the heart cell membrane.

Like a type of door, sodium channels allow sodium ions to flow into nerve cells through tiny pores.

For example, if a magnetic field is strong enough to attract or repel ions such as sodium and chloride in the blood, these ions may eventually encounter the walls of the blood vessels, move more rapidly, and cause an increase in tissue temperature or an increase in blood flow.

Lactic acid counters this fatigue by interfering with the flow of chlorine ions - effectively lowering the amount of sodium current necessary for muscle activation.
