Quizplus · Accepted Answer

Novocain is a local anesthetic that works by blocking sodium channels in nerve cells, preventing the entry of sodium ions and stopping the transmission of action potentials. This prevents the nerves from sending pain signals to the brain, resulting in numbness and pain relief. Therefore, option D - attached to sodium channels blocking sodium from entering and stopping the action potential from sending a pain message - is the correct choice.
