Multiple Choice

Which description best describes the mechanism by which local anesthetic drugs work?

• A) Anesthetic drugs bind to the sodium channels,the influx of sodium is interrupted,the action potential cannot rise,and the signal conduction is inhibited.
• B) Anesthetic drugs bind to the potassium channels,the influx of sodium is interrupted,the action potential cannot rise,and the signal conduction is inhibited.
• C) Anesthetic drugs bind to the sodium channels,the influx of potassium is interrupted,the action potential cannot rise,and the signal conduction is inhibited.
• D) Anesthetic drugs bind to the sodium channels,the influx of sodium and potassium is interrupted,the action potential cannot rise,and the signal conduction is inhibited.

Definitions:

Overload Protection

A safety feature designed to protect electrical circuits from damage caused by excessive current flow, typically via circuit breakers or fuses.

Overload Unit

A device or component in electric motors designed to protect them from running over their designed load for too long, preventing overheating or damage.

Normally Closed

Refers to a switch or relay that is in a closed (conducting) state when at rest, opening only when activated.

Overload Contacts

Electrical contacts designed to open or close in response to an overload condition, providing protection to circuits and devices.
