The ideal of anarchism is a society in which all individuals can do whatever they choose, except interfere with the ability of other individuals to do what they choose. This ideal is called anarchy, from the Greek anarchia, meaning absence of government.ut anarchy is not perfect freedom. It is only the absence of government, or coercive establishments. To show that perfect freedom is impossible is not to argue against anarchism, but simply to provide an instance of the general truth that nothing is perfect.
Cerebral spinal fluid (CSF) collection. Cerebrospinal fluid (CSF) collection is a test to look at the fluid that surrounds the brain and spinal cord. CSF acts as a cushion, protecting the brain and spine from injury. The fluid is normally clear. It has the same consistency as water. The test is also used to measure pressure in the spinal fluid.
Normal pressure hydrocephalus is a brain disorder in which excess cerebrospinal fluid accumulates in the brain's ventricle, causing thinking and reasoning problems, difficulty walking and loss of bladder control. About.PH is called normal pressure because despite the excess fluid, cerebrospinal fluid pressure as measured during a spinal tap is often normal. As brain ventricles enlarge with the excess cerebrospinal fluid, they can disrupt and damage nearby brain tissue, causing symptoms of NPH.
