There are five main senses, all of which work together to allow the body to “sense” the surrounding world. All of these senses send information to the brain. In turn, the brain interprets the information as needed. Although all of these senses are important, eyesight stands out as the most important.
What Makes Sight Possible?
There are many factors that work together to make sight possible. Although different muscles and nerves are needed to send images, the main organs dedicated to this sense are the brain and the eye itself. Without one of these vital parts, the world around us would be dark.
The eye is considered one of the most complex parts of the body. This is due to all of the different parts of the organ, numbering in the billions. This organ is held in place by the surrounding muscles, which also serve to move the eye as needed. Images are seen by the eye and projected towards the retina. The retina then converts the images into electrical impulses that can travel through the optic nerve to the brain.
