Neuron+-+OV

toc =Introduction=

Imagine your brain watching TV. And he uses a satellite TV provider, but not just any satellite, your brain uses a neuron satellite, the most powerful of its class. Like a satellite and a TV, a neuron detects and sends a message to your brain, so your brain can learn what's happening outside of the body, and control the organs and muscles and react.

=What is a Neuron= The neuron is made of many parts, but it has two major parts, the **axon**, and the **cell body**. The axon transports the signal through the cell. The cell body is where most of the organelles are found, and the **dendrites** are also found there, which are the little things that detect the signals. The layout of a neuron is basically like this (see figure 1) These may also be one of the most complex and longest cells in your body, They are the longest cells in the body, because they have to transport signals from all over the body. They can be up to a meter long!! The main neuron is in your spine, which then branches out to the other parts of your body. This neuron is called the **cervical nerve**. It is the one that connects to the brain and sends all the signals to it.

=What do they do/How do they work= = = The neuron detects the signal using its dendrites, sort of like a satellite dish, then it passes a signal as an electrical impulse through the axon, which is is covered in the **myelin sheath**, which is a gel like coat that amplifies the speed of the signal being transported, then it goes to the axon ends, which at the end there is a microscopic gap called the **synapse**. It then transforms the electrical signals into a chemical signal, called **neurotransmitters**, which passes through the synapse, then it goes into the **neuro receptors**, which are little holes that accept the neurotransmitters and spark another electrical signal as seen in Figure 2 it stimulates the neuron to create another electrical signal, which starts the neuron process all over again, which the same process keeps on repeating until it reaches the brain, which analyzes the information, reacts, and sends a signal back which allows you to react to the situation.

= = = Types of Neuron =


 * __Types of Neurons__ || __What they do__ ||
 * Sensory Neurons || Control the senses of your body ||
 * Motor Neurons || Control the muscles of the body ||
 * Interneurons || Control the thoughts and memories of your body ||

What Neurons do is transfer signals from a part of the body, to another. But they are all different depending on what they control, for example, = = =Neuron Diseases=


 * __Neuron Disease__ || __Its symptoms__ ||
 * Amyotrophic lateral sclerosis (ALS) || Interrupts all communication to motor neurons. ||
 * Progressive bulbar palsy || Disables some facial nerves. ||
 * Polio || Destroys motor neurons ||
 * Neurotoxin || Destroys the motor neuron tissue ||

=Conclusion=

That is why neurons are one of the most important/useful cells in your body, for they transport signals from your other organs to your brain, and then back.
