Question

Quizplus · Accepted Answer

Opiate receptors are not limited to a single type or location in the CNS. They are found throughout the brain and spinal cord, and their distribution varies depending on the specific subtype of receptor. This variation in receptor subtypes and distribution is important for the diverse effects of opiates, such as pain relief, euphoria, and respiratory depression. Additionally, the receptors that opiates act on are not the same as those acted on by endogenous opioid peptides, which are naturally produced in the body. Lastly, cocaine does not act on opiate receptors, but rather on neurotransmitter transporters like the dopamine transporter.
