Vision is one of the key sensory systems that primates rely on to achieve remarkable success throughout life. Vision, as depicted by the authors of dictionary.com refers to sensing with eyes (dictionary.com, 2017). The sensory system vision, has several key components and receptor cells involved in order for the eye to communicate information to the brain and through the rest of the body. Throughout this paper, a clear and precise explanation of what those key components are will be discussed, as well as how the brain interacts with the images portrayed by the eye.

[Body 1] The sensory system of vision is composed of many key components, receptors, and organs, all of which work in unison to address light waves from the surrounding world (Huffman, …show more content…

The visual cortex inside the occipital lobe is mainly responsible for vision and visual perception of the surrounding world, which in this case is a toy car, and is positioned at the posterior end of the brain. After the image of a car is processed through the visual cortex, the occipital lobe then sends neural impulses of the image to the frontal lobes. The two frontal lobes are the most complex and intricate lobes of all of the sensory systems. Upon arrival of a neural impulse, the frontal lobes are responsible for translating the neural impulse and coordinating messages to the rest of the body in order for a reaction to occur (Huffman, 2015). In the example of the toy car, the neural impulse is presented to the frontal lobes before it is processed through a higher function such as thinking. It is in this function that a human mind can determine the toy correctly. The frontal lobes are also responsible for two other functions including speech production and motor control (Huffman, 2015). Continuing with the example of the toy car, after the image of the car has been processed through higher thinking, a motor control impulse can be sent from the frontal lobes in order to push the toy car forward. A third impulse, speech production, will also be sent from the frontal lobes, which would include some sort of speech indicating …show more content…

Within the retina, there are cones which are responsible for housing the three color receptors; red, green, and blue. Color blindness is genetic and is commonly caused by one of the three color receptors missing. In a recent interview of Jay Neitz, an ophthalmologist at the University of Washington argues that the genes for the color receptors green and red are found closely together in the X chromosome and therefore are often found to be diminished (Hambling, 2013). The interview continues to indicate that this type of color blindness is more common in males due to the lack of X chromosomes. Males only have to have one gene missing from the X chromosome for color blindness to take effect, whereas females have two X chromosomes with twice as many color receptors as men (Hambling, 2013). Neitz’s research in color blindness is a continuing work of art. So far, Neitz has been able to cure color blindness in squirrel monkeys by injecting a virus into their genes which ultimately split up the green color receptor into two and change half into the missing red color receptors (Hambling, 2013). Although the results have been successful and stable, Neitz has yet to release the virus to human testing, due to the lack of a zero risk factor (Hambling, 2013). This type of research could ultimately evolutionize the medical field and be the link to
