Neurons+-+CT

=Introduction= Neurons are like phone chargers that send a messages from one place, the wall, to another place, your phone. **Neurons** travel throughout your body sending messages so your body can move and react. The impulse enters the neuron through the dendrite, through the cell body and then pulled out of the cell body with the axon. Without the billions of neurons in your body, your heart wouldn’t know to beat and your lungs wouldn’t know to control your breathing. =What is a Neuron?= The human body has billions of cells and neurons are one of them. Neurons are also called nerve cells and these cells are a necessary part of the nervous system. Neurons can send messages electrically or chemically throughout your body so you can react. Neurons are so important because the make you move, speak, and breath. Without neurons you wouldn’t be able to know how to relate to events that are happening around you. Neurons look alike to other cells, yet the have dendrites on each end. There are different types of neurons. The sensory neurons let our body know about our surroundings. There is the mot or neurons. This neuron brings the messages from our brain to different muscles, so you can react and move. Watch this [|video] to learn more about how neurons work. =Structure of Neurons= A **dendrite** is like a branch that moves impulses toward the cell body. The **axon**, connected to the cell body, sends impulses away from the cell body. The **cell body**, also called the soma, is the center of receiving and getting impulses. The cell body also uses energy to control the growth of the neuron. These three structures make up a neuron. They work together to send electronic messages throughout your body. There's an extremely small space in between the dendrites of one neuron and the dendrite of another neuron. This space is called the **synapse**. This is the a diagram of all the parts that make up a neuron.

One cell body is a ball shape and is 1/1000 of an inch wide. The axon (nerve fiber) is like a phone cord, it helps to send the message from the cell body to the dendrites on the opposite side of the axon. Most neurons have approximately six dendrites. Each dendrite is about 1/50 of an inch in length. These work as messengers, sending impulses all throughout your body. The book, Cell Communication Understanding How Information Is Stored and Used in Cells, stated "the neurons inability to reproduce". This is important because there are billions of extremely small neurons of your body and none of those neurons can reproduce. =How do Neurons Work?= Neurons are like wires, sending an electrical message from one place to another. When someone hits you, a message is sent to your brain through pathways provided by the nervous system. These pathways are called neurons. A neuron has dendrites that are connected to the cell body. The cell body is then connected to an axon, connected to more dendrites. Dendrites, the cell body and the axon all work together to send a message from one part of your body to your brain. The brain will next send another message to a part of your body, letting it know how to react. According to, World Book Online, these nerve impulses are able to be sent along nerve fibers as fast as 3 to 300 feet per second. There are about 100 billion neurons in the human body, yet not one of the neurons touch each other. The synapse is the space between each neuron. Once the message reaches the end of a dendrite, it sends transmitters that go from the end of a dendrite through the synapse, to the dendrite of another neuron. media type="youtube" key="vyNkAuX29OU" width="410" height="233" **How Different Parts of Neurons Help You?** Have you ever wondered how your fingers know how to move when you're typing or how your legs know to put one foot in front of another in order to walk. Well, this movement happens because of the neurons inside of you. There are multiple types of neurons that help you in different ways. Neurons and the nervous system help your heart beat and help messages send throughout your body. This happens in order for your body to react and help your lungs so you can breath easily. One type of neuron is the sensory neuron. This neuron picks up a signal from around the body and sends a message into a nerve impulse. Another neuron is the internal neuron that carries the message from one neuron to another. As well as the internal neuron, there is also the motor neuron that sends impulses to glands and muscles. These three neurons help you communicate to your peers, react to your environment and heal from an injury. =Conclusion= Neurons are extremely important. Yet the neurons basic job is to get messages and send them throughout the body. With this in mind, there are multiple parts of a neuron and how the neuron works is very important so you can react to your surroundings. Neurons help you in many ways, yet they can also be damaged and not function properly. =References= Friedman, Michael. Understanding How Information Is Stored and Used in Cells.
