One of two pain-relieving pentapeptides produced in the body.
Closely related to endorphins and dynorphins, enkaphalins bind to mu receptors in the brain where they mediate pain and act as an analgesiac.

Endorphins and enkephalins are neuropeptides that?
Relieve Pain
Pain messages to the brain are naturally blocked by?
enkephalins
Increased levels of enkephalins will?
derease awareness of pain.
What are two of the body's natural painkillers?
Endorphins and Enkephalins
Are enkephalins and endorphins peptides that act like morphine?
True
What are the two natural painkillers produced in the brain called?
Endorphins and Enkephalins
The molecular structure of narcotics makes it easy for them to bind to the receptor proteins for?
enkephalins
Because enkephalins and endorphins often alter a cell's response to a neurotransmitter they are called neuromodulators?
TRUE.
How do opiates block pain nerve signals to the brain?
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 function of pethidine in the body?
According to how it works: (quote) Acts as agonist at specific opioid receptors in the CNS to produce analgesia, euphoria, sedation; the receptors mediating these effects are thought to be the same as those mediating the effects of endogenous opioids (enkephalins, endorphins).(end).It is agonist meaning that it helps the receptors in the brain and spinal cord to be more open to the actions of sedation and reduces the feeling of pain. All-in-all, it acts just like opium (opiate).
What chemical is released when the nerve impulses reaches the nerve endings?
Acetylcholine is NOT the only chemical transmitter released by nerve endings. There are literally dozens. Ach is only the first discovered. Others include: glutamate, aspartate, serine, gamma-aminobutyric acid, glycine,dopamine, norepinephrine, epinephrine (adrenaline), histamine, serotonin, melatonin, adenosine, anandamide, True ACh was discovered first and is not the only neurotransmitter released, BUT Acetylcholine is basically the one of most important in producing an impulse.
