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.
The fluid is cerebrospinal fluid (CSF), which also circulates over the outside of the brain and spinal cord. Brain Stem The brain stem is the part of the brain continuous with the spinal cord and comprising the medulla oblongata, pons, midbrain, and parts of the hypothalamus. Tentorium The tentorium is a fold of the dura mater, which separates the cerebellum from the cerebrum, and often encloses a process or plate of the skull called the bony tentorium.
