Question

Quizplus · Accepted Answer

Most general anesthetics work by blocking sodium ion channels, which inhibits the transmission of nerve impulses that lead to sensation and consciousness. It is unlikely that a general anesthetic would open chloride ion channels, as this would lead to an increase in inhibition and potentially cause respiratory depression. Opening potassium ion channels would also be unlikely, as this would hyperpolarize cells and decrease their excitability, which would be inconsistent with the effects of a general anesthetic.
