Final answer:

Anesthesia blocks nerve impulses, disrupting ion movement and preventing pain signals from being transmitted to the brain.


Explanation:

Anesthesia works by blocking nerve impulses from being transmitted through the disruption of ion movement across cell membranes. When an anesthetic is applied, it interferes with the normal transmission of pain signals to the brain, effectively numbing the area being treated. This mechanism prevents the person from feeling pain temporarily.
