Anesthesia is a medically induced reversible state of unconsciousness, analgesia (pain relief), amnesia, and muscle relaxation that allows doctors to perform surgical or diagnostic procedures safely. It is caused by anesthetic agents that act on the central nervous system, altering nerve signal transmission.

Mechanism:

General Anesthetics – Depress the brain and spinal cord activity, leading to loss of consciousness and sensation.

Local Anesthetics – Block nerve impulses in a specific area, preventing pain signals from reaching the brain.

Adjunct Drugs – Sedatives, opioids, and muscle relaxants enhance anesthesia effects and improve safety.

In short, anesthesia is caused by pharmacological agents interacting with the nervous system, producing a controlled, reversible lack of sensation and consciousness for safe medical procedures.
