When consciousness is lost due to hypoxia, the brain no longer communicates with the body normally and the body enters a reflexive state called '''posturing'''. Posturing results in the extreme tension of specific groups of muscles depending on which parts of the brain are denied oxygen. However, in almost all circumstances, the fingers are tightly closed into a fist. This has several '''<u>''extremely important''</u>''' implications: | When consciousness is lost due to hypoxia, the brain no longer communicates with the body normally and the body enters a reflexive state called '''posturing'''.
