Question

Nitrous oxide enters the blood by diffusion from the alveoli whilst it is being inhaled, but does not bind with hemoglobin. N2O inhibits NMDA receptors in the brain whilst simultaneously encouraging the stimulation of the parasympathetic GABA receptors. This eventually produces an ___________________ effect.

Answer 1

The correct answer would be - anesthetic effect.

Step-by-step explanation:

The mechanism of entering and affecting the CNS or central nervous system by inhibiting NMDA receptors and simultaneously stimulating the parasympathetic GABA receptors to cause an anesthetic effect in the body is explained in question too.

This mechanism is responsible for the anesthetic effect and vigorous oxide increase the release of endorphins of opioid neurotransmitters which is act as pain killers. This anesthetic effect causes less or no pain instead of a limbic depressor.

Thus, the correct answer is - anesthetic effect.
