Condenser Diaphragm-This diaphragm controls the amount of light entering the lens system. This feature is useful for viewing unstained biological specimens that are translucent. Reducing the amount of light improves contrast, making the specimen stand out against the background.
Sciatica occurs when the sciatic nerve is pinched, irritated or injured. Inflammation, arthritis or a displaced disk in the lower spine are often to blame. Doctors commonly treat sciatica with epidural injections into the spine.(The word âepiduralâ refers to a particular area in the spine.) The injections contain a steroid, which reduces inflammation. The injections can also contain a long-lasting painkiller.The different causes of sciatica may be one reason that studies come to different conclusions.The word âepiduralâ refers to a particular area in the spine.)

There are different methods used to stop sciatic nerve pain. Generally, it is advisable to try out some of the treatment options before surgery is considered. The ice pack treatment involves lying flat with two flat pillows placed under the knees. Place ice on the side where the nerve is inflamed. Place it on the lower back, the buttock on the side affected or tailbone for up to 20 minutes every 2-3 hours. This helps to decrease inflammation in the sciatic nerve and relieving pain albeit temporarily.
