A study that relates to the nervous system of the human body is called neurology. Neurology deals with the nervous system and communication in different parts of the body. It’s a new subject that explores how the human brain and nervous system works and how it is created. Now a days neurology has become a main part of medical science because it is related to roughly 70% of activities in the body. When we touch others, feel others, or think about something, these are all possible due to nervous system.

In medical science there are many subjects in which doctor can specialize. Neurology is one of them. Neurologist treat the patients that have problems with their nervous system, spinal cord or other brain problems. Neurologists deal with epilepsy, Parkinson’s diseases and hundreds of other neurological issues.

 
Anecdotal story time! My first experience with a corneal abrasion and where I learned the term was in high school. The guy sitting next to me said something “smart” to a girl across the table at lunch who proceeded to fling (poorly) a pizza crust at him which came to find me instead. As the “corneal” bit may imply, I got smacked square in the eye and couldn’t see properly for the rest of the day. When it still hadn’t fixed by the next morning I decided to see the school nurse who diagnosed it. With that said:
A corneal abrasion is a scratch on your cornea which is the clear and protective covering over your iris. It acts as a sort of window and lens to both protect and help you see. A scratched cornea can hurt a lot if it’s something like sand that’s caught in your eyelid and it’s best to touch it as little as possible. If it is from dirt or sand, flush your eye with water.
If it’s particularly bad, a doctor may give you eye drops that can prevent infection, however, scratches typically heal on their own over time (anywhere from a day to a month). If the scratch is particularly bad, however, you can risk corneal infections, cornea erosion or even scarring of the cornea. These are all of course problems that can lead to vision problems. Always check with the doctor if you think you have a corneal abrasion so it can be properly diagnosed and treated if necessary.
