During dental procedures, dentists inject local anesthetics in the nerve pathway supporting the region they are working on. These local anesthetics block Na+ (sodium) channels. Explain in detail the process of a typical action potential, and how local anesthetics prevent the transmission of pain impulses to the brain.

Topic 2: Resting membrane potential
Describe how a resting membrane potential is established in the wrong. and your answer be sure to include
A definition of membrane potential
The resting membrane potential of neurons
What does this value mean
What ions are involved in establishing the resting membrane potential? What are the General concentration effects on resting membrane potential? why? The answer should include descriptions of relevant permeabilities, equilibrium potential, and concentration gradients.
What is the role of the sodium-potassium pump in the resting membrane potential?
