What causes the inside of neuron becomes positive?
Outside a neuron, there are mostly sodium ions but some potassium ions. Inside the neuron, there are only potassium ions. Since both sodium and potassium are positive ions, and they are in a higher concentration outside the cell, that makes the outside have a more positive charge than the inside. But for all intents and purposes, the outside is positive, and the inside is negative. When the sodium ions (Na+) rush into the cell during depolarization, it causes the concentration of positive ions inside the cell to go WAY up, making the inside more positive than the outside. This means that the outside is now negative and the inside now positive.
What helps maintain the resting potential of a neuron?
During resting potential, the Sodium-Potassium pump is inactive. Therefore, it is indirectly responsible for the resting potential. However, Potassium diffuses outside the membrane via "leakage" channels, and causes the resting potential.
How is digoxin associated with hypokalemia?
Usually, hyperkalemia is associated with usage of digoxin. This is due to the blocking action of digoxin on the Na/K ase which results in accumulation of extracellular K+.Most of the times, patients presenting with heart problems are already on diuretics before they are prescribed with digoxin. Diuretics cause hypokalemia as they result in excessive excretion of K+ from the body. Hypokalemia in turn causes digoxin toxicity. Digoxin toxicity does not cause hypokalemia, but hypokalemia can worsen digoxin toxicity.
What causes positive ions to have their positive charge?
they have lost some electrons
What causes a substance to have a positive charge?
the object has to have more positive charges than negative charges.

What are the word equation for the reaction that causes potassium to tarnish?
The word equation for the reaction that causes potassium to tarnish is: potassium (K) + oxygen (O2) → potassium oxide (K2O).
What are the chemical and word equations for the reaction that causes potassium to tarnish?
potassium + oxygen --> potassium oxide
What cause potassium to be high?
what causes your potassium to be too high
Is blood pressure regulated by positive or negative feedback?
Aldosterone is both responsible for absorption of sodium and excretion of potassium. If it is regulated by the level of potassium in blood, then we have negative feedback as high levels of aldosterone causes a decrease in potassium level in blood. If it is regulated by the level of sodium in blood, the story is just the opposite and we have positive feedback. -my own conclusion from several researches-
The role of the sodium potassium pump in maintaining a cells resting membrane potential?
The relative concentration of sodium (Na+) and potassium (K+) in the neuron with respect to their concentration in the extracellular space is what causes the electrical potential and the differential concentration is established by a Na-K Atpase which exudes sodium and transports potassium into the neuron.
Rapid potassium infusion causes diastolic or systolic cardiac arrest?
Rapid potassium infusion causes diastolic and not systolic cardiac arrest.
What causes oil to accumulate between head and engine block?
An oil leak.
The diffusion of potassium out of a neuron causes it to experience?
repolarization
Why is potassium important to the cardiac muscle?
All electrolytes are important to all muscles. In the cells there are sodium/potassium pumps that must be balanced. Some electrolytes are positive and some are negative. The balance (inside the cell vs. outside the cell) causes either contraction or relaxation.
Is their a nonprescription drug that causes a positive for benzodiazepine?
What exactly do you mean by 'causes a positive?' Please rephrase your question. Thank You Is their a nonprescription drug that causes a false positive for benzodiazepine?
Why does one collapse with low blood pressure and with high potassium in the blood?
high potassium causes arrhythmias and the arrhythmias that it causes can reduce blood pressure causing someone to collapse.
