When a Neuron is resting is the inside and outside of the cell membrane positive or negative?

A neuron wouldn't be at rest if it had positive membrane potential. It would fire an action potential. If the neuron remained depolarized then it will fire controllably, and nearby cells are then at risk of being overstimulated. If this activity spreads far enough then it will lead to an epileptic seizure - which is also damaging to neurons.

The electrical charge resulting from the difference between the positive and negative ions outside and?
The resting membrane potential
When a neuron is resting the inside of the cell membrane is?
When a neuron is resting then inside of the cell membrane is more negative than outside.
When a neuron is in a resting state the majority of the particles in the fluid surrounding the neuron are?
polarized
What is the chief positive intracellular ion in a resting neuron?
The chief positive intracellular ion in a resting neuron is a potassium ion. Just inside the cell of a resting neuron, the membrane is negative.
What would be the most immediate effect of doubling the number of Na leakage channels in the plasma membrane?
The resting membrane potential would become less negative (more positive).
Compared to the inside of the resting plasma membrane the outside surface of the membrane is?
The outside is slightly positive while the inside is slightly negative.
The electrical charge resulting from the difference between the positive and negative ions outside and?
The resting membrane potential
Electrical charge resulting from the difference between positive and negative ions outside and inside the brain cell membrane is called?
Membrane potential
When a neuron is resting the inside of the cell membrane is?
When a neuron is resting then inside of the cell membrane is more negative than outside.
Why is the resting potential value of a membrane negative?
The resting membrane potential is the difference between the inside of the cell relative to the outside. The outside is always taken as 0mv. The resting membrane potential is negative because there is a higher concentration of potassium ions outside the cell (because the membrane is more permeable to potassium ions) than inside. Since potassium ions are positively charged this leads to a negative value.
If a resting potential becomes more negative what happens to the cell?
When the membrane potential becomes more negative it is being hyperpolarized. Remember the resting membrane potential is already at a negative state (~70mV). So if you are making a comparison of a membrane potential that is hyperpolarized in comparison to a resting membrane potential, the resting membrane potential is said to be more depolarized.When the membrane potential becomes more positive it is called depolarization.
When a neuron is in a resting state the majority of the particles in the fluid surrounding the neuron are?
polarized
Which condition is a neuron in when the outside of the neuron has a net positive charge and the inside has a negative charge?
resting potiental
Is the resting potential of a neuron 50-100 mV with the inside of the cell more negative than the outside?
It depends on what the sign is before your number. A positive sign in front of the number indicates that the inside of the cell is more positive when compared to the outside; a negative sign in front of the number indicates that the cell is more negative compared to the outside. The resting potential of a neuron is always negative when compared to the outside of the neuron, and usually lies around -90mV. For different cells in the body, the resting potential may vary but it will always be negative :)!
Are myocardial cells negative or positive in their resting state?
negative at a resting value of -70mV
What is the chief positive intracellular ion in a resting neuron?
The chief positive intracellular ion in a resting neuron is a potassium ion. Just inside the cell of a resting neuron, the membrane is negative.
What would be the most immediate effect of doubling the number of Na leakage channels in the plasma membrane?
The resting membrane potential would become less negative (more positive).
