Sequential access is the method of choice if you expect users to access all the content in a prescribed order. It forces users to accept your curated contribution and assumes that most users will be willing to do so. For works of fiction, many articles, or entertainment videos that assumption is accurate.
Retinal pigment epithelium: This layer lying betwen the retina and choroid, contains melanocytes that make for its characteristic black color. This pigment allows the inside of the eye to absorb stray rays of light like the black paint inside a camera or within a dark room.he eyes are housed in protective bony structures of the skull called the orbits. Each eye is composed of a tough outer layer, the sclera and cornea; a middle layer, the choroid, ciliary body and iris; and the inner layer of nerve tissue called the retina.
Layer containing blood vessels that lines the back of the eye and is located between the retina (the inner light-sensitive layer) and the sclera (the outer white eye wall).Ciliary Body. Structure containing muscle and is located behind the iris, which focuses the lens.he cornea and the lens help to focus the light rays onto the back of the eye (retina). The cells in the retina absorb and convert the light to electrochemical impulses which are transferred along the optic nerve and then to the brain. The eye works much the same as a camera.
