Q12. Pain gets picked up by receptors, and then a signal is sent to the brain which generally occurs by the neurotransmitter. generally, anesthetics work on the nerve-to-nerve part of the system. They generally stop the neurotransmitter from getting out of the cell, so that the signal can't be sent. Or they may block the receptors so that no matter how much neurotransmitter is there, the next cell never gets the message. Or they break down the neurotransmitter faster. All of these actions will stop the signal from getting from the receptor to the brain. This is how the anesthesia blocks the pain receptors.
Q13. The relatively-static membrane potential is known as the resting membrane potential. The resting membrane potential is generally at equilibrium so that it relies on the constant expenditure of energy for its maintenance Sodium-potassium pumps moves two potassium ions inside the cell and the three sodium ions are pumped out to maintain the negatively-charged membrane inside the cell; which help in maintaining the resting membrane potential

Consider the following for problems 1 through 5: The concept of electric potential difference plays an important role in the human nervous system. A nervous impulse, for example, is an action potential that results from the temporal rising and lowering of the cell membrane potential, which in turn is caused by the equally temporal influx of sodium (Na+) ions into the cell. The sodium ions enter the cell through Hodgkin-Huxley channels, named after English physiologist/biophysicists Alan Hodgkin and Andrew Huxley....
