Neurons+-+MC

= Introduction = toc The hurdles are coming up in the race. You quickly jump over them when you are as close as you can get. It takes the work of the neurons, to quickly react to the hurdle. The structure of a neuron is very important for the neuron to work properly. However, if something goes wrong in the nervous system the result is very unsettling. Neurons are very important because they are the reason you can quickly react to situations.

= Neuron Structure =

Have you ever wondered what a neuron really is and what it’s made of?Well, neurons have a large cell body with a **nucleus**.They also have thread like strings called **dendrites**, and an **axon**. Dendrites carry impulses toward the neuron's cell body. Axons carry impulses away from the cell body. According to the __Science Textbook__ “A neuron can have several dendrites but only one axon.” Axon and dendrites act like siblings, because even though they aren't that much alike they work together to make good things happen. Axons and dendrites are not a lways called their real name like some people they have a nickname, the dendrites and axons “nickname” is **nerve fibers**. Nerve fibers are often arranged in parallel bundles covered with connective tissue. Some neuron bodies form a **ganglia**. Ganglias are when the neuron body form a cluster.

= How Neurons Work =

You may think neurons have a very dif ficult job but really it is as simple as the abc’s. Neurons carry messages through the nervous system, this is called **nerve impulse**. According to Neuroscience for kids, “Neurons communicate with each other through electrochemical process.” When you learn things, messages move from one neuron to another, over and over. Then the brain creates connections between neurons so things become easier to understand. Neurons receive information and send the information to other neurons, muscles, or glands. There are also different types of neurons that have their own role in the nervous system. **Sensory neurons** take information from the eyes, ears, tongue, and skin to the brain. **Motor neurons** carry messages away from the brain and back to the rest of the body. These neurons work together to help the nervous system.


 * Neurons and Diseases **

Have you ever wondered why people get certain diseases? Well, according to @http://learn.genetics.utah.edu/content/cells/badcom/ “In fact, most diseases involve at least one breakdown in cell communication.” A disease formed by cell breakdown is ** cancer **. When a cell starts to grow uncontrollably it can cause cancer. When a nerve cell breaks the messages don’t go through to the brain. To learn more about what causes cancer watch the video below.

Why Neurons are Important
You’ve read a lot of different things about neurons so far, and you are probably wondering why they are so important that you are reading about them. The neuron is the fundamental unit of the nervous system. According to brainfacts-the neuron “The brain is what it is because of the structural and functional properties of the interconnected neurons.” Neurons are the reason you can understand things. They are the reason when you touch something hot your hand pulls away as fast as possible. To learn more click on this link @http://www.biologyreference.com/Mo-Nu/Neuron.html

= Conclusion = In conclusion, neurons do more than you think even when you think they aren't doing anything. They are working in your body to help you whether it’s by bringing messages to the brain and to the body, or helping you understand math problems. The neuron structure is perfectly designed to do the job that they are made to do. You may think neurons have a simple job but it takes a billion neurons to create the brain what it is = = = = = References =
