A | B |
olfactory system | system which gives you your sense of smell |
olfactory epithelium | cluster of olfactory sensors in the roof of the nose. |
cila | small hair like structures in this area which greatly increase the surface area of the olfactory epithelium. |
olfactory glands | a mucus producing layer below the cilia which in times of a cold can become covered up with mucus not allowing you to smell. |
papillae | bumps on the tongue which house your taste buds. |
external ear | composed of the portion of the ear you see. |
auricle or pinna | external ear portion which funnels sound into the external auditory canal. |
external auditory canal | portion of ear where ear wax build up; it dead ends into the eardrum |
eardrum | membrane covered structure which vibrates from sound waves entering the ear. |
semicircular canals | three semi-circular fluid filled tubes which helps you with balance. |
cochlea | a snail shaped structure near the semicircular canals which allows you to hear. |
macula | thick, gel like fluid spot in the vestibule of inner ear which has nerve hair cells which bend and send the brain messages about how your head is tilted. |
otoliths | ear stones which roll about in the inner ear vestibule, bending the nerve hair cells as the head moves. |
cupula | gel like area in semicircular canal with embedded hair sensors which bend as the fluid in the semicircular fluid moves about in the canals. |
sclera | white outer portion of eyeball |
cornea | clear window like structure in front of your eye. |
pupil | the opening surrounded by the iris of the eye. |
aqueous humor | moistens the back of the cornea and the iris. |
retina | located at the back of the inside of the eyeball where its rods and cons allow for sensing incoming light into the eye. |
fovea | area where color sensing cones are more concentrated |
colorblind | the inability to fully or partially determine colors |
astigmatism | a misshaped cornea leading to a visual defect. |
nearsighted | also known as myopia cause by elongated eyeball or corneas that bend light too strongly. |
farsighted | also known as hyperopia; occurs due to shortened eyeball or cornea which doesn bend light properly. |
blind spot | area in eye where the nerve enters the back of the eyeball and thus there are no cones/rods for vision in this spot. |
binocular vision | ability of eyes to work together to locate objects more accurately. |
pinkeye | when the conjunctiva of the eye becomes infected |
conjunctiva | a protective covering over the white part of the eye. |
