| sclera | Thick, tough membrane in the outer eye layer; supports eyeball structure. |
| CORNEA | Transparent anterior section of the eyeball that bends light in a process called refraction. |
| refraction | Process of bending light rays. |
| eyelid | Movable covering over the eye. |
| conjustiva | Mucous membrane lining the eyelid. |
| choroid | Thin posterior membrane in the middle layer of the eye. |
| ciliary body | Thick anterior membrane in the middle layer of the eye. |
| pupil | Black circular center of the eye; opens and closes when muscles in the iris expand and contract in response to light. |
| lens | Colorless, flexible, transparent body behind the iris. |
| iris | Colored part of the eye; contains muscles that expand and contract in response to light. |
| uvea | Region of the eye containing the iris, choroid membrane, and ciliary bodies. |
| retina | Oval, light-sensitive membrane in the interior layer of the eye; decodes light waves and transmits information to the brain. |
| rods | Specialized receptor cells in the retina that perceive black to white shades. |
| cones | Specialized receptor cells in the retina that perceive color and bright light. |
| optic nerve | Nerve that transmits nerve impulses from the eye to the brain. |
| eyebrows | Clump of hair, usually about a half an inch above the eye, that helps to keep foreign particles from entering the eye. |
| eyelashes | group of hairs protruding from the end of the eyelid; helps to keep foreign particles from entering the eye. |
| lacrimal glands | Glands that secrete liquid to moisten the eyes and produce tears. |
| tears | Moisture secreted from the lacrimal glands. |
| ear | Organ of hearing. |
| auricle, pinna | Funnel-like structure leading from the external ear to the external auditory meatus |
| 40 dB (10,000 times as great as 10) | A whisper-perceptible to most people with normal hearing |
| eardrum, tympanic membrane | Oval, semitransparent membrane that moves in response to sound waves and produces vibrations. |
| 60 dB (1 million times a great as 10) | Regular conversational speech |
| auditory ossicles | Three specially shaped bones in the middle ear that anchor the eardrum to the tympanic cavity and that transmit vibrations to the inner ear. |
| eustachian tube | Tube that connects the middle ear to the pharynx. |
| osseous labyrinth, membranous labyrinth | One of the two tubes that make up the semicircular canals. |
| semicircular canal | Structures in the inner ear important to equilibrium. |
| 80 dB (100 million times a great at 10) | High noise such as crowded room or heavy traffic |

| equilibrium | Sense of balance. |
| vestibule | Bony chamber between the semicircular canal and the cochlea. |
| 130 dB (10 trillion times a great as 10) | Extremely loud, can cause ear damage |
| 140 dB (100 trillion times as great as 10) | Sound of a jet engine taking off, can damage hearing |
| Motion sickness | Occurs in sudden changes of body motion when organs and equilibrium are disrupted |
| olfactory organs | Organs at the top of the nasal cavity containing olfactory receptors. |
| taste buds | Organs that sense the taste of food. |
