  3. ELEMENTS OF THE SYSTEM The nervous system elements consist of: Spinal cord Brain Sensor organs Nerves The spinal cords’ and brains’ job is to control the body's nerves and movement. The sensor nerves and organs monitor problems and conditions on the inside and the out side of your body. Then they Sense the problems and then send the information back to the brain and spinal cord . Drugs can confuse the brain and spinal cord and work them to hard trying to get rid of them YOU ARE sending stuff into the body that the brain doesn’t fully know about.

  4. HOW THE SYSTEM WORKS

  5. DISEASES Tuberous sclerosis Tuberous sclerosis is a rare disease mainly formed by genes. It is very rare to get Tuberous Sclerosis. It mainly effects the brain. It can make you go into seizes ( a bit like a fit e.g. falling off a chair all of a sudden.) Doctors will give you medication if you have this problem but can’t guarantee you won’t have it anymore. Mostly it starts at the age of 2 and it can stay with you for life. Doctors have been working very hard with scientist for a very long time but have not managed to find a cure to this disease. Aphasia Aphasia is a disease that causes loss of speech. There are lots of different types of Aphasias. Anomic Aphasia is the least severe type of Aphasia. Anomic Aphasia is a type of disease that muddles up your words and can't pronounce them the way you want them to come out. People with Anomic Aphasia are normally really good at reading and understanding peoples speech. Most of the time they have trouble with writing. At the moment the doctors can’t find a treatment and have no idea what the cause is. Scientist are pretty shore that it has something to do with the cells in our body’s.

  6. DISORDERS Meningitis Meningitis is a strong heat rush that spreads around the lining of the brain and spinal cord. The disease is mainly caused by bacteria. Pneumococcal meningitis happens when bacteria has broken into the blood stream, the bacteria moves through the blood stream trying to infect the meninges ( the meninges protect the spinal cord and brain) the thing that makes the meninges so useful is the stuff that’s inside them CSF which protects the brain like a cushion from physical damage. Once recognised that you have the disease you will be given treatment on a drip and antibiotics depending on how bad the damage your treatment will change. Cerebral palsy Cerebral palsy is the most common physical disability in childhood. Every fifteen hours an Australian child is born with cerebral palsy. Cerebral palsy happens during pregnancy. Medical scientists haven't found a cure to this disorder . Cerebral palsy is a disorder that effects the cerebral a part of the brain. One in five hundred babies are diagnosed with cerebral palsy. 1 in 5 people with cerebral palsy can’t talk.

  7. ILLNESSES Encephalitis: Encephalitis is brain inflammation(swelling and pain) it is normally caused by an infection. It’s very rare but can cause major brain damage or death. While experiencing encephalitis you may have trouble sleeping a high fever and a stiff neck. The exact cause is unknown but it might have something to do with the flu. Epilepsy: Epilepsy is the most common type of seizure and illness. It is more dangerous than normal seizure as it can be controlled by antibiotics, but if the antibiotics are not working you may have to have surgery. Epilepsy can happen at any age. This illness may not be permanent condition but for a lot of other people it is.

  8. CANCER Cancers of the brain and nervous system are the second most common type of childhood cancer. Leukaemia is the first. Cancers of the brain and nervous system are normally treatable. Lymphoma is a diseases which cancer cells form in the lymph system. Lymphocytes travel in and out of the central nervous system. Primary CNS lymphoma can start in the brain, spinal cord and meninges. Primary CNS lymphoma can also start in the eye because the eye is so close to the brain.

  9. IMPORTENCE OF THE SYSTEM The central nervous system is made up of the brain and spinal cord if we didn’t have these we wouldn’t be able to live. These parts were put inside our body for a reason. Scientists still aren’t entirely shore if we would be able to live without this system. Scientist’s have found that when you are a baby if your nervous cells, brain and the spinal cord haven’t formed properly than you are most likely to have a medical issue or problem

  10. BRAIN www.focusededucation.com Sleeping brains Most people spend a third of there lives asleep. When you are asleep your body goes in and out of consciousness. Sometimes you feel as if you are floating in the air. Then your heartbeat starts to slow down and your mussels relax.at this stage even the slightest noise would wake you. After this has happened your eyes closes tightly shut and you would need a louder noise to wake you. Twenty to thirty minutes later you will be in a deep sleep you may even start to sleep talk or sleep walk. Then this pattern reverses. It continues all night. Even though you don’t think that you are awake your brain is awake. The brain can only sleep for 20 -30 minutes at a time, all of these events happen because the brain makes it happen. This has been proven by a group of scientists.

  11. The Cerebrum and the Cerebellum Cerebrum The cerebrum is the brains thinking area.it also is the biggest part of the brain and takes up four fifths of the brain. The cerebrum looks like a crinkled walnut. the reason why the folds and creases are needed is to make room for the brain cells. The cerebrum is divided into to halves. Cerebellum The cerebellum is the brains movement and control area. Cerebellum means ‘little brain’ and is at the back of the head and under the cerebrum. The size of the cerebellum is only about a tenth of the size of the cerebrum.

  12. Memory sound smells and tastes bring back memories that you have forgotteg

  13. CELLS The type of cells in the nervous system are neurons. There is about 100,000 million neuron cells in the brain. The brain is not only made up of neurons, packed between these cells are neuroglial (nerve glue) cells. Neuroglial cells support the frame work and take up about half of the brain. A neuron is made up of three parts. The first part of the cell is the body. It contains the nucleus

  15. Spinal cord The spinal cord is a long bundle of nerves, coming from the brain it is called the spinal cord because runs on the inside of the backbone(spine.)if people could cut through their spinal cord they would see a greyish H- shape, through the middle of their spinal cord. The edges of the spinal cord are a whitish colour. The white stuff around the spinal cord is called axons. Axons is made of thousands of nerve cells. Like the brain the spinal cord is wrapped in three layers of meninges. The spinal cord is the main connective cord between the brain and the body. Scientists say that the average length of an adult spinal cord is 40cm long and that the spinal cord ways around 30g. Scientists think that it is strange that the spinal cord is more than three quarters water as that is a very large amount.

  16. QUIZ What colour would the H shape be if you cut through the middle of your spinal cord ? • Black B. Pink C. Grey Answer C . Grey What is the brain and spinal cords job • To control the body’s movement B. To monitor problems C . To send information to CNS Answer A. To control the body’s movement
