Morphine (and other opioids) bind to enkephalin and endorphin receptors, activating (agonizing) them to result in a net inhibition of nociception (pain sensation).
These receptors also increase activity in the mesolimbic brain, which is responsible for inducing pleasure states and creating habit-forming and addictive behavior.
Norepinephrine and epinephrine "signals" are downmodulated so that pulse, blood pressure, and anxiety are reduced.
obialee like i dont even know anymore renow. like 7
There are no known drug interactions between opiates and NuvaRing
Opiates block the pain signals to the brain - therefore the the brain has reduced sensitivity to the pain.
You mean dopamine. Opiates cause your brain to release your dopamine supply which is what causes the euphoria.
there are places on certain nerves that reconginze opiates
How does a brain tumor affect the Brain?
No Suboxone will not block the use of opiates on a drug test. It will still show up, but you won't get the feeling from the opiates. You will however get into trouble if you are being prescribed Suboxone.
Endorphins, the natural chemical in your brain that produces pain relief. It also effects the dopamine levels of the brain, which control how happy and euphoric you feel. If you take enough opiates over a long period of time, the brain stops naturally producing these two chemicals, because it gets used to the boost the opiates given to it. That's why it's so difficult to come off of opiates. You feel depressed and in pain, because your brain is not used to producing these chemicals on their own anymore. It takes time for the brain to heal and to eventually produce these chemicals normally again.

Stimulants and depressants have opposite effects on the brain. Stimulants activate the central nervous system, while depressants (as their name implies) depress it.
Yes. The tetosterone levels decrease
Never
yes it does affect the brain in many different ways
