The human eye diagram is a visual depiction of the human eye. There are six extraocular muscles that control eye movements. Dimension of adult eyeball . [Image will be uploaded soon] Parts of the Human Eye. The pupil’s function is to adjust the amount of light entering the eye. The internal limiting membrane separates the retina from the vitreous humour. Thus potential differences are generated in the photoreceptor cells. It is composed of epithelial cells that have large amounts of clear cytoplasm in the form of fibres. Oculist doctor sign. The light rays pass through comea, aqueous humour, lens and vitreous humour and focus on retina where they generate potentials (impulses) in rods and cones. Eye Diagram. This is in accordance with the trichromacy theory. The cornea is one of the most sensitive regions of tissue in the entire body, owing to the fact that it has man… On their free edges, there are outgrowths of hairs— the eyelashes. CC BY-SA 3.0 The lacrimal gland secretes tears which are composed of water, salts and bactericidal protein called lysozyme. Label this diagram of the … 04:29. Royalty-Free Vectors, Illustrations and Pictures at Low Prices. Human eye looking the copyspace. This layer contains the cell bodies of ganglion cells. As we know, human eyes have remarkable power of accommodation by changing the convexity of the lens. Schematic diagram of the human eye in french, Ce fichier est disponible selon les termes de la licence, {{Information |Description=Schematic diagram of the human eye in french |Source=*. The space between the lens and retina is called the vitreous chamber which is filled with a transparent gel called the vitreous humour. The iris controls the amount of light entering the eye by the radial muscles contracting in dim light and the circular muscles contracting in bright light. Human Eye Diagram [Image will be Uploaded Soon] (The structure of the human eye is shown above in the image.) They produce an oily secretion which serves to lubricate the corneal surface and hold a thin layer of tears over the comea. A small oval, yellowish area of the retina lying exactly opposite the centre of the cornea is named the macula lutea or yellow spot which has at its middle a shallow depression, the fovea centralis. The rods are processes of rod cells and cones are processes of cone cells. Which part of the male reproductive system store the sperm? These cells form numerous protoplasmic processes that extend through almost the whole thickness of the retina and form external and internal limiting mem­branes. Human eye anatomy, retina. It is this membrane that becomes inflamed in conjunctivitis or “pink eye”. 2. This attribute of the eye is called the accommodation of the eye. Privacy Policy3. The cornea admits and helps to focus light waves as they enter the eye. The conjunctiva helps to protect the eye ball and keeps it moist. The aqueous humour helps to maintain the shape of the front part of the eye and provides nutrients to the lens and cornea. Attached to the ciliary body are the suspensory ligaments, which are in turn attached to the cap­sule that surrounds the lens of the eye. An artery and a vein also pass through the optic disc. They open into the follicles of eye lashes. It is just reverse to the monocular vision, as in many animals like rabbit, in which each eye focuses its own object and both the eyes cannot focus on one object. The human eye goes on to blink at an average of 4,200,000 times every year. It is a transparent, biconvex, elastic structure that bends light waves as they pass through its surfaces. In bright light the pupil is constricted. The retina is the neural and sensory layer of the eye ball. The outer fibrous coat— sclera, cornea. Human eyes are capable of detecting over 10 million colors. Beginning from the external surface (choroid side), the retina consists of the following layers: This layer lies close to the choroid.
