During depolarization, sodium (Na) rushes into the neuron through Na channels (at the Nodes of Ranvier between the bundles of myelin "insulation"). Less Na in the extracellular fluid would mean there would be less to rush in. So, the neuron would not be depolarized as well. The resting membrane potential would be more positive on the inside.
In excitable cells, it would lead to a decrease in the size of the action potential but would have no effect on the resting membrane potential. (Ganong Physiology, Chapter 3)
Resting membrane potential is maintained as long as the sodium potassium transport pump is functioning properly. If it is blocked, the cell membrane depolarizes.
A semi-permeable membrane. Does cross - membrane transit of glucose need active transport,

If you were a protein destined to reach the plasma membrane and you were making your way through the Golgi when suddenly Golgi trafficking was blocked at the trans face, what would happen to you?
The nervous system would not work if ion channels were blocked. It would be like parking your car on a hose and trying to get water out of the hose.
A membrane that lets some substances pass through but not others is known as a semipermeable membrane. Other terms that describe this type of membrane are: selectively permeable, partially permeable, or differentially permeable.

Ether prevents the action potential, by opening potassium ion pores, which allows the escape of potassium from the neurons, which results in hyper-polarization of the neuron, thus preventing the action potential from occurring.

no, a nerve that is blocked by anesthetic works by sopping that never firing or recieving impulse
Ether blocked the impulse transmission.

Osmosis, in botany and chemistry, is the process by which some unwanted elements or molecules in a solution are blocked by a membrane that other substances are allowed to pass through.
Waste can pass through a membrane due to its size and composition. Membranes have small pores or channels that allow smaller molecules or ions to pass through, while larger molecules or particles are blocked. Additionally, the chemical properties of the waste may also play a role in its ability to pass through a membrane.
If it is blocked at home your parents blocked it, but if it is blocked at school the blocked it because it was a game.
If the auditory tube were blocked, it would not be possible to equalise the pressure on both sides of the tympanic membrane. If external pressure then declines, the pressure in the middle ear would be greater than that on the outside, forcing the tympanic membrane outward and producing pain.
