It is light sensitive and acts as a film of a camera. retina b: chorold C. ciliary body d. Iris 2. a. The lens is attached to the ciliary body by ligaments. Eyeball,is a hollow sphere that composed three tunics,or coats, and its interior is filled with fluids called humors that help to maintain its shape. What is the innermost layer of the eye called? The primary layers of the retina from outermost surface to innermost surface: ... it is also dark with melanin which decreases light scatter within the eye. Retina. And the three muscles of the second layers are work together. entering the eye focuses on the retina producing images. What are the four different layers the retina compromises of? These photo receptors are known as cones and rods. The orbit is the bony eye socket of the skull. It is the light sensitive part of the eye. The retina contains photo receptors that detect light. The outermost layer, called the sclera, is what gives most of the eyeball its white color. The nerve layer lining the back of the eye. Epithelium is the thin outermost layer of fast-growing and easily-regenerated cells. posterior 5/6 of the vascular layer contains blood vessels for all 3 layers helps absorb random light to it does not scatter. The iris consists of two layers: the front pigmented fibrovascular layer known as a stroma and, beneath the stroma, pigmented epithelial cells.. It bends or refracts light. The eyeball is a spherical structure measuring about 2.5 cm in diameter. Retina: a light sensitive layer that lines the interior of the eye. *Specialized cells involved with vision *Rods are used for black and white vision "night vision" *Cones are used for color vision "day vision" How are rods and cones distributed? The five senses include sight, sound, taste, hearing and touch. Seen anteriorly as the"white of the eye". The anatomy of the eye includes auxiliary structures, such as the bony eye socket and extraocular muscles, as well as the structures of the eye itself, such as the lens and the retina.

Connected to the sclera are the extra-ocular or extrinsic muscles of the eye. Outer Layer. The stroma is connected to a sphincter muscle (sphincter pupillae), which contracts the pupil in a circular motion, and a set of dilator muscles (dilator pupillae) which pull the iris radially to enlarge the pupil, pulling it in folds. The retina at the back of the eye is essential for all vision. Cones, on the other hand, function best in bright light. The eyeball has three layers, each of which has several important structures that are essential for the sense of vision. The retina is a nearly transparent sheet of tissue continuous with the optic nerve in the back of the eye and extending forward as the inner lining of the eyeball. Fovea. The vascular layer protects portions of the eye. The retina contains nerve cells that transmit signals from the retina to the brain.
