Many people think the human eye views the images and objects of the world around us, but this is not necessarily the case. Through my studies as a nursing student, I have learned so much about how the human body works together in just about every bodily process and that our vision is no exception. The eye does not see actual objects so much as it just intercepts the light an object emits or reflects. It is here where the eye then works as a pathway for the light to be converted to an electrical impulse and transmitted to the brain. Then, in the brain, the object is converted into the image that we perceive as our vision. Through my research paper I will introduce the parts of the eye most important in vision, provide a more in-depth description of how the light intercepted by our eyes is turned into the images we see, and give further explanation on how our eye color is represented and how it may affect one's personality or other body systems. .
Did you know that the human eye is so sensitive that in total darkness the healthy eye can see a single candle flame flicker from 30 miles away (Wolchover, 2012)? Many people value their sense of sight above all other senses, as we use it in every single thing we do from writing a paper, to driving a car, to perceiving the safety of the area around us. As a nursing student at RMU, I am going to share with you the anatomy and physiology of the human eye, as well as a more in depth explanation of our eye color. The human eye is the most active muscle in the body. It is constantly shifting to keep objects clearly focused (Montgomery, 2014). The eye begins to develop at only 2 weeks post conception, and this means that most of us began eye development before our existence was even acknowledged. Our eyes grow from about 18mm as a newborn to 25mm by age 7 or 8, when the reach their full grown adult size (Jarvis, 2012, p.284). The most important structures of the eye, going from the outside inward, include: the cornea, which is the translucent covering over the eye; followed by the pupil, or the black part of the eye which is where the light enters and is focused on the retina.

I got to cut open the piggy, looking at the anatomy of the pig, and comparing the pig to a human. ...
Not only was he interested in painting and sculpturing, which is what he is probably primarily known for, but also showed great interest in architecture, mechanics, sculpturing, and the study of anatomy.

Each value began to express how ...
People believe that their strong knowledge of anatomy and physiology is due to their practices of embalming of the dead, which was a ritual for the Egyptians since prehistoric times.

They all propose that human life is more important than animal life. Humans have a god-given authority over other animals, and humans eat animals and use them for work (Cothran 51). ... Animal Experiments are used for education to learn about anatomy and physiology of the animal body (McCoy 28). ... Substances such as soap, oven cleaner, eye shadow, furniture polish, and hairspray are tested wastefully because doing the experiments on animals does not help prevent or treat human illness or injury (PETA). ...
