Opiates bond to µ-opioid (mu) receptors located on the subsynaptic membrane of neurons in the spinal cord and brain that are involved in the transmission of pain impulses. These neurons would normally have pain impulses suppressed by the release of enkephalins such as [met]enkephalin and [leu]enkephalin.

What is the major switch area of the brain?
I'm assuming that you mean the thalamus, which is where the signals going to your brain are flipped and sent to the other side. This is why the left side of your brain controls the right side of your body and vice versa.
What is assay of opiates?
I'm going to assume 'assay of opiates' means one has tested positive for opiates in their system. Opiate's can range from the prescription hydrocodone to heroin.
How can I see yall guys?
When light hits the retina (a light-sensitive layer of tissue at the back of the eye), special cells called photoreceptors turn the light into electrical signals. These electrical signals travel from the retina through the optic nerve to the brain. Then the brain turns the signals into the images you see.
If the ventral roots are destroyed can impulses reach the spinal cord?
In short, Yes.A majority of the "signals" that travel through the ventral roots are motor "signals" going out to the periphery from the spinal cord. As such, the signals have already "reached" the spinal cord from the brain or another region of the spinal cord.Thus, A ventral root lesion will interrupt signals from reaching the periphery.
Why is it bad to have a sugary sweet before going bed?
The treat will raise your blood sugar level (no surprise there) and that signals the brain that it is time to be awake and alert! Not a good sleep hygiene strategy.
Will lead tape stop a cell phone from going off in metal detector?
No lead tape will not stop a cell phone from going off in a metal detector. Lead tape is used to add weight to a golf club and does not block electromagnetic signals. Cell phones are designed to transmit signals and lead tape will not be able to block those signals. If you want to stop your cell phone from going off in a metal detector there are several things you can do: Turn off the phone before entering a metal detector Put the phone on silent or vibrate mode Put the phone in airplane mode Keep the phone out of reach of the metal detectorThese methods should help to prevent your cell phone from going off in a metal detector. If you are still having trouble you may want to consider using a different phone or device that does not emit signals.
Why does ear piercing hurt?
Ear Piercing hurts because they use a needle to make a hole in your ear but your nerves dont know that you want this done so they send signals to your brain telling your brain that something is inflicting damage upon you and your brain makes that part of you that is getting peirced send out signals which is pain. Obviously it shouldn't hurt if you get your ear numbed before peircing...
Does the human brain produces its own natural opiates that elevate mood and ease pain?
Yes, they're called "endorphins". There is currently much research going on to see if they can be voluntarily brought to bear by people who suffer from chronic pain, as one example.
Which region of the brain helps control respiration?
The Medulla Oblongata The medulla oblongata helps control the body's autonomic functions (things you don't need to think about to perform) like respiration, digestion and heart rate. Also acts as a relay station for nerve signals going to/from the brain
How can an eye react quickly to movement?
Our eye reacts quickly to movement by our eyes responding to movements and for our eyes being able to spot the different things going on and then reacts and sends signals to the brain which then tells you how to react to it.
How sounds are convertd into electrical signals going to the brain?
There are several (a lot) of tiny hair like structures inside the ear will vibrate in response to certain sound frequencies. When a hair vibrates, it stimulates a particular cell which sends a signal to the neurons next to it, to the brain. The brain takes all of the inputs and can interpret that as sounds and frequencies. Louder sounds will cause it to vibrate more, so the brain can interpret that as well.
