Document Summary
Human neuroscience chapter 9 and 10 study guide. Fovea: area in the retina made of closely packed cone cells. Optic nerve: (2nd) cranial nerve that transmits impulses to the brain from the retina at the back of the eye. Optic disk: the point of exit for ganglion cell axons leaving the eye. No rods or cones overlying the optic disk, thus corresponds to a small physiological blond spot in each eye (located right at the entrance of the optic nerve) Macula: small area in the retina that contains special light sensitive cells and allows us to see fine details clearly. Visual field: refers to the total area in which objects can be seen in the side (peripheral) vision as you focus your eyes on a certain point. Rod photoreceptor: photoreceptor cells in the retina of the eye that can function in less intense light than the other type of visual photoreceptor cells.
