Exam 10: Opioids

Endogenous opioids are:

Opioid receptors are:

Opioid drugs promote dopamine release in the nucleus accumbens by inhibiting GABA neurons in the ventral tegmental area.

What affect on reinforcing effects will the combination of an opioid agonist with an opioid antagonist have?

Increased neurotransmission by met-enkephalin and leu-enkephalin would imply increased synthesis of:

Describe how activation of G-protein-coupled inwardly rectifying K+ channels (GIRKs)promotes inhibition of a neuron.

Activating opioid receptors in the nucleus accumbens produces reinforcing effects.

The drug salvinorin A binds to the ________ opioid receptor.

Opioid found in the body are called naturally occurring opioids.

Describe the ways that opioids act on reward circuitry.

A neurotransmitter that is involved in the reinforcing effects of opioid agonists is:

The symptoms of an overdose from an opioid receptor agonist may be reduced if the user is given a(n):

The slang term robotripping refers to psychedelic effects derived from:

Increased synthesis of propiomelanocortin would lead to greater activation of opioid receptors by:

How do opioid agonists produce analgesic effects?

While the mechanisms through which opioid neurons inhibit the activity of neurons remains unclear,one known mechanism is:

In the U.S.,due to the Drug Addiction Treatment act,specialized clinics are needed for prescribing:

A narcotic implies that drugs activating opioid receptors can produce:

If an increased synthesis of proopiomelanocortin occurred,which of the following types of receptors would likely see increased activation?

The ________ pathway delivers pain signals to the brain.
