Sound is a pressure wave that is created when a vibrating object (stereo) sets a medium (air) in motion. The vibrations create a variation in density causing the medium to vibrate back and forth.
Local anesthetics produce a reversible blockade of impulses conducted along neural pathways by attaching to the inactivated and open states on voltage-gated, sodium channels in the axonal membrane. This binding prevents the sodium voltage-gated channel from undergoing a conformational change, and thus inhibits sodium ion influx into the axoplasm and depolarization of the nerve fiber.
