The μ-receptor
A) has been linked to hallucinations and dysphoria.
B) overlaps with the κ-receptor in its distribution in the nervous system.
C) is found in the hypothalamus and pituitary.
D) plays a role in analgesia and the rewarding effects of morphine.

Question

Quizplus · Accepted Answer

The μ-receptor is primarily associated with analgesia (pain relief) and the rewarding effects of opioids such as morphine. A and B are incorrect as hallucinations and dysphoria are more closely linked to the κ-receptor, and while the κ-receptor does overlap with the μ-receptor in certain regions of the nervous system, this is not the primary characteristic of the μ-receptor. C is partially correct, as the μ-receptor is present in the pituitary gland but is not restricted only to these structures.
