Myopia or nearsightedness
Can’t see close objects but objects further away look blurry
nasopharynx
Where the nasal cavity blends into the throat above the palate in the mouth
night blindness
People who simply do not make enough photo pigments to see low light
Odorant
Any substance you can smell
olfactory epithelium
the layer of sensory receptor cells responsible for the sense of smell
Olfactory recess
The only place in the nose capable of smell

A depression in the skull
otolaryngologist
Ear
Oval window
A membrane on the surface of an inner ear structure called the labyrinth
Pain receptors
Respond to excess stimulation
papillae
Little projections like tufts in a carpet; not taste buds but folded mucosa
Perspire
Producing a sweat that will kill you as it evaporates from the skin’s surface
Photo pigments
Make the retinal cells sensitive to light
Photokeratitis or snow blindness
Where are the sunlight burns your eye
