In the human body, there are a connection between our eye and brain that gives us the ability to see colors and shapes that make out the environment around us by the rods and cones within our eyes. These rods and cones are very effectively doing similar jobs, but are different in many ways, including: number of cells, shape, number of bipolar neurons, black and white/color vision and sensitivity to light (Cameron, 2016). “Our body converts light with ideas, of visually understanding features and objects in the world” (How Vision Works) and can see things that a computer can not see. The connection between the eye and the brain is very powerful and there is tons of information about the brain we do not know but, can also determine tons about …show more content…
The simplest organ of vision is found in the branchiata” (The Development of the Eye, p. 194). When the eye becomes more developed you can start to differentiate the part of the eye: the mantle lined with a number of epithelial cells, nucleus and a deposit of pigment (The Development of the Eye, p. 194). This is the beginning of vision and how the eye is developed. From there, you can determine all the different parts of the eye when it is fully developed and how it works, including: the Ciliary muscles, Suspensocy ligament, Cornea, Iris, Pupil, Anterior, Aqueous Humor, Lens, Schlemm’s canal, Posterior Vitreous Humor, Sclera, Choroid, Retina, Fovea, Optic nerve and Blind spot (Cameron, 2016). The eye has many parts and starts with the suspensory ligaments that connect the lens to the ciliary muscles that pull on the lens and change the shape. This changes when you focus on objects that are distant and close. These ligaments and muscles pull on the lens according to the distance between you and what you are looking at. This also goes into a deeper discussion on nearsighted and farsighted people (Cameron, …show more content…
From this, the Neural Pathway begins in the retina of the eye and moves on to the optic nerve and continues on to the Optic Chiasma. Following, the Thalamus Superior Colloiculi moves on to the pons and into the visual cortex of the brain where all things are processed so you can see. Your visual cortex is also known as the Occipital Lobe, one of four cerebral lobes of the brain. The other lobes are the Frontal lobe, Temporal Lobe and Pariental Lobe that all have a protective sac-like covering of the whole entire brain. This visual cortex is connected through the corpus callosum so that they eye can register the object in front of them and go through the Neural Pathway (Cameron, 2016). They eye alone is considered a photoreceptor. The lense focuses images and the retina layer detects light rays. The retina is in the back of the eye ball along with the fovea; the conical depressed region in rich cones. Next is the fovea which is the middle layer of the eyeball that is rich in blood vessels where the vitreous humor is. This humor is a trasparent jelly marterial of the posterior chamber that is inside the eyeball. Following, towards the front of the eyeball, are where the ciliary muscles and suspensory ligaments are that pull on
