Study Notes
Eye Structure Terminology
-
Ciliary Body: A circular structure that connects the iris to the choroid; it plays a crucial role in adjusting the shape of the lens for focus and produces aqueous humor.
-
Cornea: The transparent front layer of the eye; responsible for most of the eye's optical power, it refracts light entering the eye.
-
Iris: The colored part of the eye surrounding the pupil; controls the size of the pupil and thus regulates the amount of light that enters the eye.
-
Lens: A transparent structure located behind the iris; changes shape to focus light onto the retina for clear vision.
-
Aqueous Humor: A clear fluid produced by the ciliary body; fills the anterior and posterior chambers of the eye, maintaining intraocular pressure and providing nutrients to the eye tissues.
-
Sclera: The white outer coating of the eyeball; provides protection and structural support to the eye.
-
Vitreous Body: A gel-like substance filling the space between the lens and the retina; helps maintain the eye's shape and provides support to the retina.
-
Retina: The light-sensitive tissue located at the back of the eye; converts light into neural signals that are sent to the brain for image processing.
-
Choroid: A layer of blood vessels located between the retina and sclera; provides nourishment to the retina and absorbs excess light.
-
Optic Nerve: A bundle of nerve fibers that transmits visual information from the retina to the brain; essential for vision.
-
Optic Disc: The point on the retina where the optic nerve fibers exit the eye; lacks photoreceptors, creating a blind spot in the visual field.
