I chose to focus on the Nervous System. The Nervous system is made up of the central and peripheral nervous system that are linked with one another to create sensations throughout the body. The Central Nervous system is made up of the brain and spinal cord, while the Peripheral Nervous system consist of nerves that are enclosed in axon that connect the Central system to the rest of the body. Both the brain and the body can transmit signals from to the other, however, the names differ depending what does the sending. Nerves that send signals from the brain are called motor nerves, while nerves that are sent from the body are called sensory nerves. The Peripheral sends signals to the Central about a sensation that they are currently feeling to then receive a sensation back to help that part of the body how to react to the situation.

Myopia is an eye disease that elongates the eyeball and affects the way light reflects off of the eye making it difficult to focus on objects that are further away from the viewer. This is a very common refractive error all around the world. According to a study by the National Eye Institute , Myopia was something that affected 25% of the US population from 1971-72, however, this number grew to 41.6% from 1999-2004. Recent studies suggest that the cause for the rise in Myopia could be the fact that children are spending less time outside. This could probably even go deeper to children spending too much time on electronic devices and the amount of blue light that they emit. Normally, Myopia is nothing more than just a minor inconvenience to those that have it, but sometimes it can be so severe that it is considered a degenerative condition and is also the leading cause of legal blindness. It 's relatively rare for this to happen, however having it affects about 2% of Americans and most doctors believe it to be
