How is temporal bone ache to return a responsibility?

summary

Temporal bone pain first comes from the injury of body tissue. You can eat more light things, which produce some pain substances and stimulate the pain receptor. The stimulation of these chemicals turns into impulses in nerve cells, which are activated by A δ And C nerve conduction to the spinal cord, brainstem, hypothalamus and brain. There was no individual difference in the transmission of pain to the thalamus. It's the brain that determines an individual's response to pain. So here's how temporal bone pain is going on? I hope this problem can help some people.

How is temporal bone ache to return a responsibility?

First, when the tissues of the body are injured, whether they are bitten, burned or hit by mosquitoes, inflammation will occur. The substance causing inflammation but not pain will overflow from the tissue; Even if the concentration is very low, it is enough to cause pain.

Second, there are many kinds of these substances, including amines, proteolytic substances, polypeptides, prostaglandins, hydrogen ions and so on. The function of histamine is to increase the permeability of blood vessels, make tiny pores appear in tiny blood vessels, and make white blood cells and antibodies in blood enter the tissue from blood vessels.

Third, prostaglandins are known as pain relief substances; It does not cause pain in itself, but it promotes inflammation. The purpose of inflammation is to increase the concentration of local leukocytes, antibodies and immune factors, protect tissues, remove wastes and make appropriate repair.

matters needing attention

As mentioned above, pain nerves are conducted by two different nerves, due to a δ The conduction velocity of nerve fiber is faster than that of C nerve fiber. The injured can feel two different kinds of pain after injury: fast pain and slow pain. Rapid pain, also known as first pain, is caused by A δ Fibers conduct first. It has a clear scope; The pain is sharp but short, and the slow pain is also called the second pain. The faster pain appears later. The range of pain is uncertain and lasts for a long time.
