Vagus Nerve

The vagus nerve “wanders” (vagus, Latin for wander) through the body and affects all major organs and their functioning. It is the second largest nerve in the body, second only to the spinal cord. Originating deep within the brain, the vagus nerve wanders through the neck, affecting speech, voice, continues through the thorax affecting all the organs of the body, and continues to the pelvic floor.
