Lighting: The film uses only the natural light of the environment. Lessons Status. Get this resource as part of a bundle and save up to 21%. External components include structures which can be seen on the exterior of the eye, and internal components include structures … The transparent structure inside the eye … Poor vision in dim light, called nightblindness, results from vitamin A deficiency. Rods and cones also differ in the sharpness of the perceived images, or visual acuity. 806 8067 22 4 of 8. Who is the choreographer in Within her eyes? Without treatment, cataracts eventually cause blindness. The iris is a thin diaphragm composed mostly of connective tissue and smooth muscle fibers. Table 1. The lens or its capsule slowly becomes cloudy and opaque. The cornea helps focus entering light rays. Janie tells the stories contained within the novel to Pheoby during the course of an evening. Thus, if a point of light stimulates a rod, the brain cannot tell which one of many receptors has been stimulated. Structure of the Human Eye The eye is a hollow, spherical structure about 2.5 centimeters in diameter. One set of ciliary muscle cells extends back from fixed points in the sclera to the choroid coat. Updated: May 30, 2020. docx, 40 KB. Her eyes are “nothing like the sun,” her lips are less red than coral; compared to white snow, her breasts are dun-colored, and her hairs are like black wires on her head. Home \ courses. For example, the shortest wavelengths of visible light are perceived as violet, and the longest are perceived as red. The eye, lacrimal gland, and associated extrinsic muscles are housed in the orbital cavity, or orbit, of the skull. Please refer to Component 2: Dance appreciation for more information about the structure of the written exam. Because of this, impulses from a group of rods are conducted to the brain on a single nerve fiber. In bright light, nearly all of the rhodopsin in the rods of the retina decomposes, greatly reducing rod sensitivity. ... GCSE Dance New Spec 12 mark structure strips ». When the ciliary muscle relaxes, tension on the suspensory ligaments increases, and the lens becomes thinner and less convex again. Within Her Eyes presents a daringly intimate glimpse into a secluded world of fragile dependency. Learn vocabulary, terms, and more with flashcards, games, and other study tools. However, if the tension on the suspensory ligaments relaxes, the elastic lens capsule rebounds, and the lens surface becomes more convex—focused for viewing closer objects. 1 . Photoreceptors are modified neurons of two distinct kinds, as Figure 7 illustrates. Lack of the vitamin reduces the supply of retinal, rhodopsin production falls, and rod sensitivity is low. Refraction occurs when light rays pass at an oblique angle from a substance of one optical density into a substance of a different optical density. The ciliary muscle controls the actions of the suspensory ligaments in accommodation. Schematic Diagram of the Human Eye: Structure of the eye and closeup of the retina. The film is shot to reflect the dark atmosphere of the inspiration. Start studying Fact file- within her eyes. The film is shot to reflect the dark atmosphere of the inspiration. The story is told in the context of a "frame." Within Her Eyes Setting. Course Content . Normal eye refraction (perfect image on the Macula’s Fovea). However, the impulses leaving in response to each activated photoreceptor deliver only a fragment of the information required for the brain to interpret a complete scene. The film was shot in Wales in mostly grey, gloomy weather, which gives it a sombre atmosphere. The lacrimal apparatus consists of the lacrimal gland, which secretes tears, and a series of ducts that carry tears into the nasal cavity (Figure 3). Unlike the motion picture image, however, the image that forms on the retina is upside down and reversed from left to right. From this region, the visual impulses enter nerve pathways called optic radiations, which lead to the visual cortex of the occipital lobes. The retina contains the cells that sense light (photoreceptors) and the blood vessels that nourish them. The fovea centralis, the area of sharpest vision, does not have rods but contains densely packed cones with few or no converging fibers. You can also use your PowerPoint from last The light-sensitive biochemical in rods is called rhodopsin or visual purple. Muscles Associated with the Eyelids and Eyes. Synopsis. Just click the "Edit page" button at the bottom of the page or learn more in the Plot Summary submission guide. It looks like we don't have a Synopsis for this title yet. It bends or refracts light. Be the first to contribute! At the end of Flow One and Flow Two. The epithelium on the inner surface of the ciliary body secretes a watery fluid called aqueous humor into the posterior chamber. What is the company for Within her eyes? Convergence of impulses is less common among cones. Lens (also called crystalline lens). Because the optic disc region does not have photoreceptors, it is commonly known as the blind spot of the eye. Ciliary Body Structure containing muscle and is located behind the iris, which focuses the lens. From there the tears flow into the nasolacrimal duct, which empties into the nasal cavity. Structure: It starts with a prologue followed by 6 sections, defined by changing locations, physicality and music that reflect the developing relationship. The convex surface of the cornea refracts light rays from outside objects. Their Eyes Were Watching God. For the penultimate section it switches to a hand held camera giving a much more raw and unstable feeling reflecting the female character’s emotional state. The choroid coat, in the posterior five-sixths of the globe of the eye, is loosely joined to the sclera and is honeycombed with blood vessels, which nourish surrounding tissues. KO---Within-Her-Eyes. If all three sets of cones are stimulated with equal intensity, the person senses the light as white, and if none are stimulated, the person senses black. For the dance James wanted to create a love story with a twist. The choreography contrasts the folding in to him with the pulling away to highlight the pull she feels to her late lover whilst trying to allow herself to move on with the man who cares so much for her. These proteins, along with the absence of organelles that scatter light (mitochondria, endoplasmic reticula, and nuclei), account for the transparency of the lens. It is opaque due to many large, disorganized, collagenous and elastic fibers. Filmed by Scratch. James Cousins company. Get Revising is one of the trading names of The Student Room Group Ltd. Register Number: 04666380 (England and Wales), VAT No. Bundle. A prologue. To understand how the eye sees, it helps to know the eye structures and functions: Cornea: Light enters through the cornea, the transparent outer covering of the eye. 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. GCSE Dance New Specification - Knowledge Organisers. The most sensitive part of the retina is a small area called the macula, which has millions of tightly packed photoreceptors (the type called cones).The high density of cones in the macula makes the visual image detailed, just as a high-resolution digital camera has more megapixels. enable_page_level_ads: true © Copyright Get Revising 2021 all rights reserved. 1 . The impulses are conducted away from the retina along the optic nerve into the brain, where they are interpreted as vision. Showing all 0 items Jump to: Summaries. The suspensory ligaments attached to the margin of the capsule are also under tension. In post - production the film was given a slightly dark undertone enhancing the mood further. The majority of the film is shot with the camera on a track, giving a very smooth quality. A central artery and vein also pass through the optic disc. When the muscle contracts, the choroid coat is pulled forward and the ciliary body shortens. Cones provide sharp images, and rods provide more general outlines of  objects. James then pieced these segments together into a structure that reflected the narrative arc of the story. Info. The pathways begin as the axons of the retinal neurons leave the eyes to form the optic nerves. Photoreceptors are stimulated only when light reaches them. Iris. More Movement Style in WHE: Learn. February 2016. 1 of 7. What is the date of the first performance in Within her eyes? The Bluest Eye (1970), the first novel by Toni Morrison. Tears also have an enzyme (lysozyme) that kills bacteria, reducing the risk of eye infections. 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). They are closely associated with an adjacent layer of retinal pigment epithelium (RPE) that absorbs light the photoreceptors do not absorb. Staging/set:The film is set in remote locations to give the feeling of isolation and highlight the characters separation from society. The spaces within the eye are filled with fluids that help maintain its shape. Both rods and cones contain light-sensitive pigments that decompose when they absorb light energy. When a cone is stimulated, the brain can pinpoint the stimulation more accurately. The iris divides the space (anterior cavity) separating these parts into an anterior chamber (between the cornea and the iris) and a posterior chamber containing the lens (between the iris and the vitreous body). It looks like we don't have any Plot Summaries for this title yet. The darkness of his costume links him to the earth whereas the lightness of her costume gives her a more delicate feel. As soon as the eye moves, it re-adjusts its exposure, both chemically and geometrically, by … The male dancer never manipulates, he only responds to her moves, showing his devotion to her. A lens with a convex surface (as in the eye) causes light rays to converge. More than 90% of the proteins in a lens cell are lens crystallins, which aggregate into fibers. The colored part of the eye. A prologue followed by 6 continuous sections, defined by changing locations, physicality and music that reflect the developing relationship. Within Her Eyes: Style and Skills. The sclera makes up the posterior five-sixths of the outer layer of the wall of the eye. The melanin that these cells produce absorbs excess light, which helps keep the inside of the eye dark. Bright light stimulates the circular muscles to contract, which decreases the amount of light entering the eye. The overall effect is one seamless journey. KO---Within-Her-Eyes. James Cousins. Most of the fibers, however, enter the thalamus and synapse in its posterior portion (lateral geniculate body). The iris controls the size of the pupil, through which light passes as it enters the eye. With the pigment of the choroid coat, the retinal pigment epithelium keeps light from reflecting off surfaces inside the eye. Dim light stimulates the radial cells to contract, which increases the amount of light entering the eye. The radial set (pupillary dilator) is composed of specialized contractile epithelial cells (myoepithelial cells). Its wall has three distinct layers—an outer (fibrous) layer, a middle (vascular) layer, and an inner (nervous) layer. The retina contains the cells that sense light (photoreceptors) and the blood vessels that nourish them. Contact Miss Francis. Outline. Thus, fibers from the nasal half of the left eye and the temporal half of the right eye form the right optic tract, and fibers from the nasal half of the right eye and the temporal half of the left eye form the left optic tract.
