Why do you think it might be a problem if the sodium-potassium pumps in neurons did not function properly?

Magnesium deficiency may lead to a number of pathologies, but a more direct answer would have to do with the sympathetic nervous system.  The more proximal effect of a change in the sodium-potassium pump is a partial depolarization of neurons, because of an inability to maintain the ionic gradient critical for hyperpolarization...If an increased number of sodium ions enter the neuron, then it becomes much more excitable, and will fire more frequently.  This can lead to over activation of the sympathetic nervous system, which will, among other things, cause vasoconstriction (narrowing of the arteries), increased heart rate, etc- It would be a classic stress response, and lead to high blood pressure, which in turn can cause congestive heart failure and hemorrhagic stroke.  If there is a significant malfunction of this enzyme in the central nervous system (i.e. brain and spinal cord), it would cause death.

Sodium can cause the body to retain water.If your kidneys can't eliminate enough sodium, the sodium starts to accumulate in your blood. Because sodium attracts and holds water, your blood volume increases. Increased blood volume, in turn, makes your heart work harder to move more blood through your blood vessels, increasing pressure in your arteries. Certain diseases such as congestive heart failure, cirrhosis and chronic kidney disease can lead to an inability to regulate sodium.\n\nYour body needs some sodium to function properly. \nIt helps maintain the right balance of fluids in your body \nAssists in transmission of nerve impulses \nIt influences the contraction and relaxation of muscles

A deficiency in potassium and other salts can also lead to severe muscle contractions. Also hydrate regularly. Is this due to athletic workouts?

I've heard it can sometimes be a potassium deficiency.  Eating more bananas would help with that.

It might be hereditary or some organs in our body are not functioning well though we might not know it.

Simply there is a domain a cell can do. Different cells do different things. You can't get a neuron to make insulin.

a loss of potassium overly stressed, sweating, not eating enough potassium rich foods, what helps me is a apple cider vinegar tablet every morning. hope this will give you something to check into.

none salt cause high bloodpressure and stress

I would hope if you had ct scan it would have picked up on brain tumor,it is possible that this all related to your hypertension.people that have brain tumors have severe ha,due to brain swelling,seizures visual problems,coordination problems,speech problems,sleep alot

It can be several things. The most probable is magnesium or potassium deficit or restless leg syndrome

There are any number of things it could be, a trapped or compressed nerve comes to mind first.  You need to have it checked out, better safe than sorry.

The neuron actively builds the ionic gradients by pumping specific ions into or out of the cell.  Na+ and K+ are the major players, Cl- less so, and Ca2+ the least important.  Na+ ions are pumped out and K+ ions are pumped in by the Na+/K+ ATPase.  At rest, there are a lot of Na+ ions outside the cell and a lot of K+ ions inside the cell.  The charge imbalance means the cell has an electrical voltage across its membrane.\n\nWhen the neuron is activated, it opens up ion channels that allow these ions to suddenly flow into or out of the cell down their gradients.  For example, Na+ ions are suddenly going to rush into the cell and K+ ions will rush out of the cell slightly later.  The result is a sudden change in the electrical voltage of the cell membrane.  This is the basis of how nerves generate electrical impulses.

Both potassium and sodium are equally critical to propagation of an action potential- However, high external potassium will cause depolarization of nerve endings, while high sodium will not-This is because the membrane is permeable to K+ ions, thus they will enter the cell (nerve ending) suddenly, causing the opening of voltage-dependent sodium channels, thus sodium rushes in, thus depolarization.  Sodium ions are excluded from the cell under resting conditions in the absence of depolarization, so adding sodium extracellularly will not induce an action potential.

It can be just periodic fluid retention from too much sodium.  It could indicate some degree of heart failure, or could have to do with pregnancy.  Have this person check with the doc, as the underlying cause may need immediate attention.  Also the fluid retention may be in other areas also, such as around the heart and lungs, and could cause significant problems.

Since the ions are slightly unbalanced between the outside and inside of the cell, a membrane potential develops.  Na/K ATPase continously pumps Na out of the cell and K into the cell, so that the K concentration is aobut 30x bigger inside than outside and Na is about 20x less inside the cell.  and it's an active transport (ATPase...).if it werent' there, it would lead to a flattening of the ion gradient and the membrane potential would break down

sodium/ potassium pump is what enables any living cell that thrives in water media (that includes all human cells) to keep an isotonic concentration of the positivelly charged sodium ion vs. its counteractive potassium equivally monocharged cation. This is insured by an active transmission of the potassium cation into the cell, with the concurring release of the sodium cation out of the cell, against all principle of osmotic pressure. This requires important usage of energy, as supplied by the continuous Krebs cycle, generating the higher energy levelled ATP. This pump is always active and its dysfunctionment will result into the misconcentration of the solutes in the cell, that will be fatal

the only thing that I can think of, is that when you are putting so much water into the fly it messes up it's electrolytes...therefore the nerves can't do anything because they will never reach their threshold and have an action potential.  Mostly the potassium and the sodium, and so when you put salt (which contains sodium) on the fly is causes the electrolytes to re-balance.\nMaybe the fly isn't really dead...maybe it's just paralyzed?\n\nThis is just a theory since I've never heard of this phenomenon myself.
