What is pain physiology?
The feeling of pain has evolved to ensure that organisms avoid harmful or fatal stimuli. There is a strong emotional component, but also a real physiological basis for this feeling. Studies of pain physiology revealed that pain is scanned and transferred to the brain, similar to other physical feelings such as temperature or touch. They exist throughout the body, with the exception of the brain, and they are free nerve endings. In the presence of painful stimuli they cause nococeptor cell shooting. There may be many potential causes of pain because mechanical, chemical, electrical and biological stimuli can lead to firing.
After the initial firing of the Nococeptor, the signal is transmitted to other cells that transmit information to the spinal cord and brain. According to the research of modern physiology of pain, pain is perceived when these signals reach the central nervous system. Thalamus is the first area where pain is reduced.
The signal is then transmitted to the limbic system that is responsible for the emotional ASPect of pain, and at the same time on the cortex. There is interpretation and pain perception. Some parts of the bark, including the primary sensory cortex, allow the location of the source of pain.
In physiology of pain there are two different types of nerve fibers that represent two types of pain. The first type, called fibers, transfers rapid information about sudden pain such as cut or burns. Fast transmission allows reflective reactions, such as a departure from the cause of pain before the brain perceives the pain itself.
Another type of nerve fiber important in pain physiology is a smaller C fiber. These fibers transmit reports after the initial feeling of pain and convey dull pain or mild burns that follow sharper initial pain. Messages from C threads are transmitted more slowly because of their size and because their axons are not wrapped in myelin. It is assumed that they are responsible for some feelings cHronic pain.
various objects of painkillers were obvious by understanding physiology of pain. Many pain treatments focus on inhibition of pain signals concerning the emotional component of pain, including narcotic relief from pain. Despite the counter lighteners, pain often reduces the inflammation and transmission of initial signs of nococeptor pain. Other painkillers include antiepileptic drugs that seek to prevent the perception of pain from explanation of cells in the nervous system.
