CPO- Anatomy of the eye| 100% verified Aqueous Humor - fluid produced by the ciliary body. Fills anterior chamber providing nutrients for the lens and cornea. Reponsible for maintaining intraocular pressure and the only fluid continually produced in the eye. Choroid - A thin vascular layer between the sclera and the retina. It supplies blood to the retina and conducts arteries and nerves to other structures in the eye. It is pierced from behind by the optic nerve and is firmly adhered to the sclera. Ciliary Muscle - Smooth muscle portion of the ciliary body, which contracts to assist in near-vision capability Conjunctiva - The thin membrane that lines the eyelids and covers the white of the eye is the.... Cornea - Clear membrane at the front of the globe covering the iris, pupil, and anterior chamber. Responsible for 60% of the eyes focusing power. Contains 5 layers Crystalline Lens - Forty percent of the optical focusing system, immediately behind the iris, aka Lens Medial Rectus - Moves eye inward, Adduction. Inferior rectus - Moves eye down and turns medially Lateral rectus - Moves eye out, Abduction Superior rectus - (#1) elevates eye and turns it medially Superior oblique - Moves eye down and in Inferior oblique - most inferior muscle in the eye. elevates eye/ turns it laterally Extraocular Muscles - Muscles that move the eyeball. Fovea Centralis - area consisting of a small depression in the retina containing cones and where vision is most acute Fundus - The interior surface of the eyeball Iris - A ring of muscle tissue that forms the colored portion of the eye around the pupil and controls the size of the pupil opening. Lacrimal Duct - tubes that carry tears to the lacrimal sac Lacrimal Gland - gland located in the upper outer region above the eyeball that secretes tears Macula - The central part of the retina- the fovea depression is at its center Nasolacrimal Duct - A duct that carries tears from the lacrimal sac to the nasal cavity Optic Disk - The appearance of the optic nerve when viewed through the pupil. The portion of the optic nerve that is formed by the meeting of all the retinal nerve fibers. It corresponds to the physiological blind spot. Optic nerve - The nerve that carries neural impulses from the eye to the brain Orbit - Eye socket. Posterior Chamber - space between the back of the iris and the front of the vitreous chamber; filled with aqueous humor Pupil - Adjustable opening in the center of the eye through which light enters Retina - Inner lining
