...liquid that flows through the anterior and posterior eye chambers in the space between the cornea and the lens.
...condition in which the eye cannot bring horizontal and vertical lines into focus at the same time, causing blurry vision, as a result of irregularities in the curvature of the cornea and lens.
...flap of cartilage and skin that comprises the outer ear; external ear, pinna. A portion of the atrium of the heart. (Sometimes used to refer to entire atrium.)
...specialized neurons concentrated in the retina's center that receive color, add visual acuity, and require a significant amount of light to function.
...condition in which light rays focus behind the retina; farsightedness. The eyeball is too short and one cannot see objects clearly.
...the "anvil," one of three tiny bones within the middle ear which are set in motion by sound waves.
...a transparent, crystalline eye structure that converges or scatters light rays before they focus as images on the retina.
the "hammer," one of three tiny bones within the middle ear which are set in motion by sound waves
organ of Corti
...small but intricate organ in the inner ear where the transmission of nerve stimuli begins
...collectively, the three tiny bones in the middle ear (the malleus, incus, and the stapes) which are set in motion by sound waves.
...drooping or sagging of an organ or part from its normal position (usually refers to eyelid)
...the innermost tunic of the eyeball that contains rods and cones and is the origin of the optic nerve. Light rays focus at the retina in normal vision.
...specialized neurons dispersed throughout the retina, suited to dim light and especially useful in night vision
...section of the inner ear that contains hairlike nerve endings that respond to movement and control the sense of balanc
...the "stirrup," one of three tiny bones within the middle ear which are set in motion by sound waves
sensation of rotation or movement of self (subjective vertigo) or surroundings (objective vertigo). (Not all dizziness is true vertigo.)
receptors are located in the areas such as the fingertips and around the lips, constantly receiving nerve impulses with regard to pain and pleasure.
