A pinched nerve is an injury to a nerve or group of nerves resulting from compression, entrapment or stretching. Numbness, tingling, burning or pain can result. In some cases, muscle weakness can also occur. Symptoms of a pinched nerve may develop gradually or can come on suddenly. Nerves can be compressed as they leave the spine; when they pass over bony prominences, through muscles, or under ligaments; or as a result of trauma.
Lungs, Lungs Diseases, Functions of Lungs. Lungs are the major organ of our respiratory system, helping us obtain oxygen and get rid of carbon dioxide. Our chest cavity houses a pair of lungs which open to the external environment through the nose and mouth. A cylindrical tube, called trachea, is the main link between the lungs and the nose and mouth.
The vital organs are the brain, the heart, the lungs, the liver and the kidneys. These are organs that a person couldn't live without if one or the pair of them were entirely removed.
