Eyes and Ears!!
| Question | Answer |
|---|---|
| Fibrous layer of clear tissue that extends over the anterior portion of the eye and is continuous with the white of the eye? | Cornea |
| Yellowish region in the retina; contains the fovea centralis? | Macula lutea |
| What eye structure is transparent, biconvex, and focuses light on the retina | Lens |
| Place where optic nerve fibers cross in the brain | Optic chiasma |
| Adjustment of the lens by the ciliary body | Accomodation |
| Photosensitive receptor cells of the retina; make the preception of color possible | Cones |
| The combining form for the ciliary body is | Cycl/o |
| The meaning of palpebr/o is | Eyelid |
| The combining form for cornea | Kerat/o |
| An eye inflammation commonly called "pinkeye" is | Conjunctivitis |
| Impairment of vision due to old age | Presbyopia |
| Myopia | Nearsightedness |
| Astigmatism | Defective curvature of the cornea or lens |
| Glaucoma is primarily diagnosed by | Tonometry |
| A blind spot; area of depressed vision surrounded by an area of normal vision | Scotoma |
| Macular degeneration produces | Loss of central vision |
| Small hard mass on eyelid; formed from sebaceous gland enlargements | Chalazion |
| Snail-shaped, spirally wound tube in the inner ear is the | Chochlea |
| Channel between the middle ear and the nasopharynx | Labyrinth |
| Myring/o means | Tympanic membrane |
| Bacterial infection of the middle ear | Suppurative otitis media |
| Tinnitus | Ringing sound in ears |
| Visual examination of the ear | Otoscopy |
| Nerve deafness occurring with | Presbycusis |
| Fungal infection of the ear | Otomycosis |
| Contains sensitive cells (rods and cones) that transmit light energy to nervous impulses | Retina |
| Contains muscles that control the shape of the lens and secrete aqueous humor | ciliary body |
| Transparent body behind the iris and in front of the vitreous humor; refracts light rays to bring them into focus on the retina | Lens |
| Jelly-like material behind the lens; helps to maintain the shape of the eyeball | vitreous humor |
| Dark center of the eye through which light rays enter | Pupil |
| Vascular layer of the eyeball that is continuous with iris | Choroid |
| Delicate membrane lining the eyelids and covering the anterior eyeball | Conjunctiva |
| Fibrous layer of clear tissue that extends over the anterior portion of the eyeball | Cornea |
| Colored portion of the eye; surrounds the pupil | Iris |
| Tough, white outer coatof the eyeball | Sclera |
| Inflammation of the vascular layer of the eye | Uveitis |
| Condition of dry eyes | Xerophthalmia |
| Outward deviation of the eye | Exotropia |
| Inward deviation of the eye | Esotropia |
| Absence of the lens of the eye | Aphakia |
| Absence of vision in half of the visual field | Hemianopsia |
| Abnormal deviations of the eye | Strabismus |
| Increased intraocular pressure results in retinal and optic nerve damage | Glaucoma |
| Localized purulent infection of a sebaceous gland in the eyelid | Hordeolum {stye) |
| Clouding of the lens causes decreased vision | Cataract |
| Retinal micro aneurysms,hemorrhages occur secondary to an endocrine condition | Diabetic Retinopathy |
| Deterioration of the macula lutea of the retina | Macular Degeneration |
