Understanding Eye Anatomy – Function Of The Optic Nerve
Our eyes help us gather information from our environment which our brain then processes so that we can make decisions based on the images we see. For example, our eyes play a major role in terms of reflex actions. For instance, if a flying object is coming in our direction our eyes send impulses to the brain which enables us to make the snap decision to get out of the way and avoid injury. Therefore, our eyes play a protective role in terms of keeping us safe in dangerous situations. There is a part of the eye called the optic nerve that plays a role in the transmission of such information to the brain. Therefore, here is some information concerning the role of the optic nerve in vision function:
The optic nerve is included among the various parts of the visual system which are responsible for recording images. Our eyes are constantly receiving light images that have been reflected off of objects. These light rays reflected off of objects enter first through the eyes via the clear transparent window of the eyes called the cornea, and in conjunction with the eye lens, focuses these light rays. These light rays are then transmitted so that they fall on the retina of the eyes. Here, they are processed and sent to the brain through electrical impulses via the optic nerve. This is done so that the brain can make sense of the images thereby converting them into the vision that we are able to see.
Therefore, we can think about the optic nerve as an electrical cable in the visual system. This is due to the fact that it can be defined as the second of several pairs of cranial nerves. This cranial nerve receives visual information from the retina and the purpose of this part of the eyes is to transmit this information via electrical impulses to the centers of the brain responsible for vision function.
This particular nerve consists of ganglionic cells or nerve cells. This part of the eye is made up of about one million nerve fibers. The optic nerve is also known as the visual neural pathway to the brain that helps the brain make sense of visual information from the retina so that we can see images clearly.
The optic nerve is known as the visual neural pathway to the brain. It processes images that have been sent to the brain through this neural pathway via electrical impulses so that the brain can make sense of this visual information and convert it into the image that we see as our vision. Without the optic nerve our brain could not make sense of images transmitted to it via the retina. Therefore, the optic nerve plays a vital role in the transmission of visual information from the retina and passes it onto the brain. Our brain then makes sense of that visual information thereby converting it into the clear images that we see.
