While the mechanisms through which opioid neurons inhibit the activity of neurons remains unclear,one known mechanism is:
A) reduced activity of G-proteins associated with opioid receptors.
B) increased influx of Cl-.
C) blockade of sodium channels.
D) the activation of inwardly rectifying K+ channels.

Question

Quizplus · Accepted Answer

The activation of inwardly rectifying K+ channels is a known mechanism through which opioid neurons inhibit the activity of neurons. This results in hyperpolarization of the affected neuron, making it less likely to fire. The other options are known mechanisms of action for various drugs or neurotransmitters, but are not specific to opioids.
