The+nervous+system

The [|nervous system] is the one that transports signals all over the body. It consists on long chains of [|neurons]. Neurons are cells with hairs that connect to the next cell. The parts are dendrites, cell body, axon, and the terminals. With long strings of neurons like this.[| Neurons] transmit nerve messages. Neurons are surrounded by [|glial cells] with support cells in the nervous system and help protect[| neurons.] The line of neurons works like this; the message is received by the dendrites, then it travels through the axon, and on the axon terminals the message is passed onto the next neuron. Huge chains of neurons are located all over your body. Neurons that are not on the brain have myellin, cells with myellin are white, neurons on the brain are grey. Everything that happens on your body is controlled by neuron paths, all the other systems like respiratory, digestive, and respiratory function with the nervous system. The spaces between the neurons is called a synapse. This system works based on an electrical impulse.

One very important disease that regards the nervous system is HIV/AIDS. It is famous for not having any cure. HIV damages your bodies immune system cells. AIDS is what doctors call HIV once it is more developed. At first you get symptoms that might not scare you like the flu or swollen glands. You might have the virus for up to 10 years with out any severe symptoms. But one you get it, it gets worse and worse every time. It will continue to get worse untill you die. The most scary part is that it has no cure. The most common way of getting infected by the virus isby unprotected sex or by using the same needle as someone who has HIV.

This image shows the main symptoms you might have while having aids on each part of the body.
