The colored ring of tissue suspended behind the cornea and immediately in front of the lens It regulates the amount of light entering the eye by adjusting the size of the pupil
Behind the cornea is the colored part of the eye, the iris The color of the iris is a result of the amount of pigment, it contains The iris contracts and expands its dilator muscles, depending on whether you are in bright light or in dim or dark surroundings By regulating the size of the pupil, the opening in the center, the iris directs light onto the retina (Marks 3)
The coloured muscular membrane which lies behind the cornea and in front of the lens which by opening or closing determines the size of the pupil and hence the amount of light entering the eye
A genus of plants having showy flowers and bulbous or tuberous roots, of which the flower-de- luce (fleur-de-lis), orris, and other species of flag are examples
The contractile membrane perforated by the pupil, which adjusts to control the amount of light reaching the retina, and which forms the colored portion of the eye
Tissue behind the cornea that gives color to the eye (i e blue eyes) and controls amount of light entering the eye by varying the size of its central opening (pupil)
The colored portion of the eye It is actually a small muscle that helps the eye adjust to different levels of light and dark When it dilates, the eye receives more light through the pupil, and when it contracts, the eye receives less light
the opaque muscular contractile diaphragm that is suspended in the aqueous humor in front of the lens of the eye; perforated by the pupil and continuous peripherally with the ciliary body; possesses a deeply pigmented posterior surface, which excludes the passage of light except through the pupil, and a colored anterior surface which determines the color of the eye
the colored diaphragm in the anterior chamber of the eyeball which contracts and expands to adjust for light intensity (See "Anatomy of the Eye" on the MD Support web site )
Pigmented tissue that lies behind the cornea that gives color to the eye (e g , blue eyes) and controls the amount of light entering the eye by varying the size of the black pupillary opening
diaphragm consisting of thin overlapping plates that can be adjusted to change the diameter of a central opening muscular diaphragm that controls the size of the pupil; it forms the colored portion of the eye plants with sword-shaped leaves and erect stalks bearing bright-colored flowers composed of three petals and three drooping sepals
The round, pigmented membrane surrounding the pupil of the eye, having muscles that adjust the size of the pupil to regulate the amount of light entering the eye
This is a structure that we see as the colored part of the eye Two muscles within the iris relax and contract the pupil so it can help control and focus the light coming in to the eye
The colored part of the eye The ring of tissue suspended behind the cornea and immediately in front of the lens Regulates the amount of light entering the eye by adjusting the size of the pupil
