how is brain protected from shock and injury
1)?? Brain is located in a bony box called skull. There are three membranes surrounding the brain called meninges. Between these 3 membranes there is a fluid called cerebrospinal fluid which protect the brain from mechanical shocks.and full for get how to keep my dog from eating cat litter jamey johnson in color chords
Your spinal cord is a glistening white bundle of nerves, which runs from your brain down a canal in your backbone. It's roughly 40cm long and about as wide as your thumb for most of its length. Like your brain, your spinal cord is part of your central nervous system. Its main function is to relay information about what's happening inside and outside your body to and from your brain. These nerves are part of your peripheral nervous system. They carry information in the form of nerve impulses from your spinal cord to the rest of your body and from your body to your spinal cord.
NCBI Bookshelf. In response to many metabolic disturbances and injuries including stroke, neurodegenerative disease, epilepsy and trauma, the cell mounts a stress response with induction of a variety of proteins, most notably the 70 kD heat shock protein Hsp The possibility that stress proteins might be neuroprotective was suspected because Hsp70, in particular, was induced to high levels in brain regions that were relatively resistant to injury. Hsp70 expression was also correlated with the phenomenon of induced tolerance. With the availability of transgenic animals and gene transfer, it has become increasingly clear that such heat shock proteins do indeed protect cells from injury.

Anatomy of the brain and spine
The spinal cord is a long, thin, tubular structure made up of nervous tissue , which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. It encloses the central canal of the spinal cord, which contains cerebrospinal fluid. The brain and spinal cord together make up the central nervous system CNS. In humans , the spinal cord begins at the occipital bone , passing through the foramen magnum and entering the spinal canal at the beginning of the cervical vertebrae. The spinal cord extends down to between the first and second lumbar vertebrae , where it ends. The enclosing bony vertebral column protects the relatively shorter spinal cord.
For woodpeckers, "thick skull" is no insult. In fact, new research shows that a strong skull saves these birds from serious brain injury. Woodpeckers' head-pounding pecking against trees and telephone poles subjects them to enormous forces — they can easily slam their beaks against wood with a force 1, times that of gravity. In comparison, Air Force tests in the s pegged the maximum survivable g-force for a human at around 46 times that of gravity , though race-car drivers have reportedly survived crashes of over G's. Researchers had previously figured out that thick neck muscles diffuse the blow, and a third inner eyelid prevents the birds' eyeballs from popping out.
Brain is covered by a 3 layered membrane called meninges. This could be the result of illness, shock, a brain injury, or a spinal injury. The brain and spinal cord are protected from injury by the skull and vertebral column.
Together, the brain and spinal cord form the central nervous system. This complex system is part of everything we do. It controls the things we choose to do -- like walk and talk -- and the things our body does automatically -- like breathe and digest food. The central nervous system is also involved with our senses -- seeing, hearing, touching, tasting, and smelling -- as well as our emotions, thoughts, and memory. The brain is a soft, spongy mass of nerve cells and supportive tissue.
