Question
Chapter 37, Problem 10TYU
Summary Introduction
To hypothesize:
How various anesthetics would block pain with the help of action potential and synapses.
Concept introduction:
If there is sufficient shifting of the membrane potential, due to depolarization, then it would result in massive change in the voltage (membrane); this is known as the action potential. Synapse is referred to as a junction that is present between two nerve cells.
