Ophthalmology
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 |
