The Anatomy of the Eye

Question	Answer
Each eye is located within an	orbit
A layer of this cushions and protects the eye.	fat
These upper and lower structures protect the delicate tissues of the eye.	eyelids
These form a protective barrier that extends outward from the eye to catch foreign substances before they come in contact with the eye.	eyelashes
The red, triangular tisse at the medial corner where the eyelids meet is called the	caruncle
This gland is located in the superior-lateral aspect of each eye.	lacrimal
The lacrimal glands continuously secrete tears that travel through the lacrimal	ducts
The tears flow into the lacrimal	sac
After the tears flow into the lacrimal sac they then flow into this duct.	nasolacrimal
The delicate, transparent mucous membrane that covers the insides of the eyelids and the anterior surface of the eye is called the	conjunctiva
This is called the "white of the eye".	sclera
This structure allows light to enter the eye.	cornea
The colored part of your eye is called the	iris
In bright light, muscles in the iris contract to constrict and decrease the diamater of the pupil. This process is known as	miosis
In dim light, muscles in the iris relax to dilate and increase the diameter of the pupil. This process is called	mydriasis
Eye color is determined by	genetics
The spongy membrane of blood vessels that is part of the internal structure of the eye is called	choroid
The extension of the choroid that holds the lens in place behind the iris is called the	ciliary body
The clear, flexible disk behind the pupil is called the	lens
The lens of the eye is surrounded by the	lens capsule
The process by which the lens changes shape is called	accomodation
The small space between the cornea and the iris is called the	anterior chamber
The very narrow space posterior to the iris is called the	posterior chamber
The clear, watery fluid that is produced continuously by the ciliary body is called	aqueous humor
The largest space in the eye is the	posterior cavity
The clear, gel-like substance that helps maintian the shape of the eye is called	vitreous humor
The geneal word for the retina is the	fundus
The thin layer of tissue that lines the curved posterior wall of the eye is the	retina
The bright, yellow-white circle with sharp edges in the are of the retina closest to the nose is called the	optic disk
The optic disk is where this structure enters the eye.	optic nerve
The optic disk is also known as the	blind spot
The dark yellow,orange area behind the optic disk is the	macula
The small depression in the center of the macula is the	fovea
Light rays entering the pupil fall on the	macula
These muscles control the movement of the eye.	extraocular
The extraocular muscles are attached to the sclera by	tendons
The retina contains special light-sensitive cells known as rods and	cones
Rods detect black and white but not	color
Cones are only sensitive to	color
