FC: Nervous System Project | By: Rachel Madsen
1: This is my nervous system project. I am going to tell you about how you can damage your brain. I am also going to tell you about the essential components of the body.which are: cerebrum, cerebellum, medulla oblongata, neuron, and the spinal cord.
2: cerebellum | The cerebrum is divided into hemispheres and has layers that are of both white and gray matter. The Cerebellum is located below and behind the cerebrum. The main function of the cerebellum is to control balance and coordination. It also controls speech, voluntary motor movement, and muscle tone.
3: The Cerebellum regulates movement of the body. It helps controls balance. It also helps your posture. | Continue.....
4: Medulla Oblongata | The lowest part of the brain is Medulla Oblongata. The spinal cord is is attached to the Medulla. The Medulla has many functions, like: breathing, rate of heart, blood pressure, reflexes, swallowing, and body temperature. These functions are very helpful to our body. Certain cells in the Oblongata Medulla's gray matter layer serve the body by controlling many of the vital functions that are very necessary for our life. | Oblongata Medulla
5: Oblongata Medulla continue.... | These include rate of breathing, heart beat, and digestion. The medulla is composed of the white and gray matter. The white is on the outside of the oblongata medulla. The gray matter serves as a switchboard for sensory messages on their way to muscle or gland.

7: NEURONS | Nerve cells are called neurons. A neuron consists of a cell body and many connecting fibers. The cell body is the control of the cell and contains the nucleus or even the center surrounded by cytoplasm. The axon is a nerve fiber that carries messages away from the cell body. Neurons can transit a signal at a fast rate.
8: Neurons continued....
9: Spinal cord | The spinal cord is a long bundle of nerves that is found within the vertebral column. There are many functions that the spinal cord has. The main functions are mostly transmission of information. This is how it happens: attached to the spinal cord are thirty one pairs of nerves carrying messages to and from your spinal cord. They reach to all parts of your body. Some of your nerves carry messages to your brain. your other nerves carry to muscle, the glands, and more body parts.
10: spinal cord continued....
11: Cerebrum | The cerebrum is the largest part of the human brain. A surface area called the cortex serves as the control board of the nervous system. Each cerebral cortex has a particular job to do. One job is to control the muscles. Its function is also one of the higher brain functions. It is the part of the brain that controls thought, memory, and the senses. The right hemisphere controls the left hemisphere. The left hemisphere controls the right.
12: Cerebrum continued.....
13: Things that can damage our brain. | Heroin | Heroin is a highly addictive drug.Brain cells can become dependent on this drug to finally where they need this drug in order to function in there daily routine. After a while your main purpose in life is to drink the drug because you are telling your brain you want the drug and then you are too addicted to stop.
14: Marijuana | Marijuana is a very bad drug. It is bad for your brain cells and will make you want more. The part that effects your emotions and memories are effected the most. It has also been known to weaken problem solving ability's. | alcohol | Alcohol effect your vision a lot. It makes your brain fuzzy and you get lots of blackouts.It also shortens coordination.
15: inhalants | This is like smelling glue, hairspray, paint. It is really bad for you and will effect you as soon as you sniff it. Some vapors go away, but others stay for a long time. The tissue protecting the nervous system is usually destroyed by inhalants. Inhalants also effects learning, remembering, and solving problems.
16: The Nervous System | The switchboard nervous system is composed of the spinal cord and the brain. If certain parts of you were injured then you would not be able to speak, think, or feel. You would be paralyzed if your spinal cord broke.The principal areas of the brain are the cerebrum, the cerebellum, and the medulla oblongata.
17: All the functions are very helpful to us and without any of these body parts we wouldn't even be alive. To protect the brain and spinal cord there are hard bones that keep them enclosed. There are three kinds of tissue like meninges. They protect the nervous system. The nervous system is very important to learn. | Continued.....
