Sodium ions probably have no function in cells. Sodium ions enters the cells by their tendency to diffuse. Potassium ions play very important role in cells. Interestingly cells spend most of there energy in keeping the sodium ions out and potassium ions inside the cells. How does cell recognise the potassium and sodium ion in fraction of second is one of unresolved puzzles of nature. ( Sodium has configuration of 2, 8, 1 and potassium ion has 2,8, 8, 1. Both has got SAME size and chemical properties.) As such sodium ions enters the cell once the excitable cells are stimulated.

Sodium ions play a crucial role in nerve cells by contributing to electrical signaling. When a nerve impulse is generated, sodium ions rush into the cell, leading to depolarization and the initiation of an action potential. This allows the nerve impulse to rapidly propagate along the nerve cell.

Which two elements are needed to help nerve cells send electrical signals?
It's Sodium and Potassium are necessary for the transmission of nerve impulses
The chief ion used to maintain the volume of fluid outside cells is?
sodium
Which atom is isoelectronic with sodium ion?
Neon is isoelectronic with the sodium ion.
Conduction of nerve impulses is possible because of the?
Conduction of nerve impulses is possible because ions in the extracellular environment versus the ions inside the cell.
How does sodium atom form an ion?
A sodium atom becomes a sodium ion, when a neutron is added to the nucleus.
What cells in animal body contain sodium ion?
almost all but some cell does not contain sodium ion.
What is a component of an animal nerve Cell membrane?
A component is the Sodium ion channel.
A sodium channel blocker would increasedecreaseserum sodium levels outside of normal resting nerve cells?
a sodium channel blocker would (increase;decrease) serum sodium levels outside of normal resting nerve cells
A nerve impulse results from?
It results from the opening of voltage-gated sodium ion channels, causing an influx of sodium ions (influx of positively-charged ions), depolarizing the neuronal membrane.
Which two elements are needed to help nerve cells send electrical signals?
It's Sodium and Potassium are necessary for the transmission of nerve impulses
What is the major positive ion outside of cells?
Sodium is the major positive ion outside the cell. Potassium is the major positive ion inside the cell.
Are nerve cells?
Nerve cells are specialized cells for neuron function by bio chemical ion diffusion to transmit electrical impulses as information from neural cortices to muscles/organs for coordination of body function.
The chief ion used to maintain the volume of fluid outside cells is?
sodium
A sodium ion differs from a sodium atom in that the sodium ion?
A sodium ion differs from a sodium atom in that the sodium ion has a missing electron electron. It has a positive charge, as opposed to the atom, which is neutral.
What minerals is the major positively charged ion inside body cells?
sodium
What colour is sodium ion?
Sodium ion is colorless.
What accounts for the resting membrane potential seen in unstimulated nerve and muscle cells?
Sodium-potassium pump
