what is CSF and in which part of the body is it made and by whom?

Cerebrospinal fluid (CSF), Liquor cerebrospinalis, is a clear bodily fluid that occupies the subarachnoid space in the brain (the space between the skull and the cerebral cortex—more specifically, between the arachnoid and pia layers of the meninges). It is basically a saline solution and acts as a "cushion" or buffer for the cortex. Cerebrospinal fluid also occupies the ventricular system of the brain and the spinal cord. It is mainly produced by the choroid plexus, but also by the ependymal lining of the brain's ventricles. The CSF is formed by the choroid plexus or the ventricles, circulates through the interventricular foramina into the third ventricle and then via the mesencephalic duct (cerebral aqueduct) into the fourth ventricle space through two lateral apertures and one median aperture, and is then absorbed by the venous system to the blood circulation.

The brain is the organ responsible for thought and other functions.  The mind is the abstract concept that is the culmination of all thoughts, not a physical object.

The plug on the end that goes into the wall!\n\nThe real answer is that every component is as important as the other.\nJust go in and snip a wire or a resistor for fun.\n\nIf I leave my brain at home I can't function, can I? Is the brain the most important organ in the human body? What if I leave my liver at home.  Soon I'm dead. How about I leave my stomach at home and go to a Chinese buffet. Gads what a mess I'd be in! So is the brain more important than the liver or stomach. Me thinks not. For any complicated organism or device to work it needs all it parts so each part is as important as the other.

the most obvious protection of the brain is the skull.  also, there is connective tissue from the skull that can help protect it.  there are three meninges, too, which kinda help to protect it.  they are the dura mater, arachnoid mater, and pia mater.  the cerebral fluid which the one person mentioned in contained between the meninges in the subarachnoid space.

Cerebrospinal fluid occupies both the ventricular system (http://en.wikipedia.org/wiki/Ventricular_system) of the brain and the spinal cord(http://en.wikipedia.org/wiki/Spinal_cord). It has many roles such as shock absorption, nutrition, waste disposal and communication (see reference 1).

liver\nliver, largest glandular organ of the body, weighing about 3 lb (1.36 kg). It is reddish brown in color and is divided into four lobes of unequal size and shape. The liver lies on the right side of the abdominal cavity beneath the diaphragm. Blood is carried to the liver via two large vessels: the hepatic artery carries oxygen-rich blood from the aorta, and the portal vein carries blood containing digested food from the small intestine. These blood vessels subdivide in the liver repeatedly, terminating in minute capillaries. Each capillary leads to a lobule. Liver tissue is composed of thousands of lobules, and each lobule is made up of hepatic cells, the basic metabolic cells of the liver. One of the liver's major functions is the manufacture and secretion of bile, which is stored in the gall bladder and released in the small intestine. Bile salts emulsify fats, a process that prepares the latter for digestion by the intestinal enzymes (see digestive system). The hepatic cells assimilate carbohydrates, fats, and proteins. They convert glucose to its stored form, glycogen, which is reconverted into glucose as the body requires it for energy. The ability of the liver to maintain the proper level of glucose in the blood is called its glucose buffer function. The end products of fat digestion, fatty acids, are used to synthesize cholesterol and other substances needed by the body. Excess carbohydrates and protein are also converted into fat by the liver. Digested proteins in the form of amino acids are broken down further in the liver by deamination. Part of the amino acid molecule is converted into glycogen and other compounds. Urea, a waste product of protein breakdown, is produced by the liver, a process which removes poisonous ammonia from the body fluids. The liver is also capable of synthesizing certain amino acids (the so-called nonessential amino acids) from other amino acids in a process called transamination. Some essential components of blood are manufactured by the liver, including about 95% of the plasma proteins and the blood-clotting substances (fibrinogen, prothrombin, and other coagulation factors). The liver also filters harmful substances from the blood. Phagocytic cells in the liver, called Kupffer cells, remove large amounts of debris and bacteria. In addition, the liver stores important vitamins and minerals, including vitamins A, D, K, and B12. Several diseases states can affect the liver, such as hepatitis (an inflammation of the liver) and cirrhosis (a chronic inflammation that progresses ultimately to organ failure). Alcohol alters the metabolism of the liver, which can have overall detrimental effects over long periods of abuse. In 1994, a bioartificial liver, part machine, part cloned living liver cells, was used for the first time. Functioning somewhat like a kidney dialysis machine, the bioartificial liver can support patients with acute liver failure until their own livers regenerate, or it can be used by patients while waiting for a liver transplant.

This is definitely a myth.  We use all of our brain.  The origin of this myth is that only 10% of our brain is made up of actual neurons in the strictest sense.  That means that only 10% of the cells in our brain are the kind that transmit signals and make us think.  The other 90% are called glia.  These cells provide the structural support and nutrients for the neurons, as well as clear away their waste and excess neurotransmitters.  These cells are "used" just as much as the other 10% though.

The brain tissue surrounding the ventricles is far from homogeneous, but can be separated into a number of connected but distinct parts. It is dominated by the massive cerebrum, or forebrain, divided neatly down its mid-line into two almost mirror-image halves, linked by a massive band of nerves, the corpus callosum. Below the cerebral hemispheres lie the mid- and hind-brains. For the first 3-4 mm below the wrinkled surface of the cerebrum the tissue is coloured pinkish grey, forming the cortex (meaning “bark”); below that, it is yellowish white. The colour of the cortex is due to its extremely rich blood supply—fully 20 per cent of circulating blood goes to supply the brain. By contrast the “white matter” is so because of the fatty sheaths, composed largely of myelin, which insulate the nerves packed inside. The geography of the cerebral cortex, defined by its ridges and clefts (sulci and gyri) provides a distinction between left and right, frontal and occipital lobes. The regions towards the mid-line are medial, towards the sides temporal, the top, dorsal, and the bottom, ventral.\n\nBehind the cerebrum lies the even more wrinkled and folded cerebellum (“little brain”) covered with its own cortex. Visible as the brain is dissected are a number of distinct structures named by the anatomists after their fancied resemblance to other natural forms—the hippocampus (seahorse), amygdala (almond), pons (bridge), medulla, and many more. Running down from the medulla and through the spine is the spinal cord, carrying nerves to (afferent) and from (efferent) the brain itself. Nerves to and from the eyes (optic), nose (olfactory), and also cranial nerves to other regions of the head run directly into the brain, not via the spinal cord. Together, brain and spinal cord form the central nervous system (CNS), to distinguish them from the nerves that connect the brain and cord with the rest of the body, called the peripheral nervous system. Because of the bilateral symmetry of the brain, each of the structures within it seemed to the early anatomists to be duplicated, one to the left and one to the right. The exception seemed to be the pineal gland, located in the centre of the brain, and it was in part because of this that Descartes, whose dualist philosophy firmly separated the human soul from the mere clockwork processes that ran the rest of the body, decided that the pineal must be the site at which the soul or mind interacted with and drove the body forward. Non-human animals, which were believed not to possess souls, he saw as entirely machine-like.\nThe current view of the brain is of an organ composed of a large number of substructures, each densely packed with neurons and their surrounding glia. Within each nucleus, and within the cerebral and cerebellar cortices, neurons are of three general types: some receive inputs from either sense organs or other brain regions; others (projection or pyramidal neurons) transmit signals out of the region, down long axons to other brain regions or, via the spinal cord or cranial nerves to the periphery. The third and much the most numerous class are the spiny or stellate interneurons, which communicate only within a particular nucleus or cortex, either with one another or with the afferent and efferent neurons.\n\nFor modern localizers, these different substructures are regarded as “centres” for particular brain functions. Of particular importance are a group of connected nuclei including the hypothalamus, hippocampus, some nuclei of the thalamus, and the amygdala, sometimes grouped together as the limbic system. These centres are particularly relevant in the context of emotion, sexual drive, hunger, and thirst, and damage to them can have profound effects. The hypothalamus also has direct neural connections with the pituitary gland at the base of the brain, the source for many important regulatory hormones, and hypothalamic-pituitary feedback processes provide a key site for
