| Question | Answer |
|---|---|
| Taste is strongly influenced by ______ and stimulation of thermoreceptors, ______, ______ | smell, mechanoreceptors, and nociceptors |
| Pathway of light entering the eye: cornea, ____, _____, _______, and the neural layer of the retina to the photoreceptors | aqueous humor, lens, vitreous humor, |
| Middle Ear (Tympanic Cavity) is Flanked laterally by the _____ and medially by the ______ and _______. | eardrum, oval and round windows |
| connects the middle ear to the nasopharynx | Pharyngotympanic tube |
| middle ear inflammation; common result of a sore throat. Most frequent cause of hearing loss in children | Otitis media |

| For a chemical to be tasted it must be dissolved in ______, move into the ______, and contact the _____. | saliva, taste pore,gustatory hairs |
| a refractive error causing the light rays entering the eye to be focused irregularly on the retina due to an abnormally shaped cornea. It causes blurred vision and discomfort. | Astigmatism |
| occurs when objects focus in front of the retina and results in seeing close objects without a problem but distance objects are blurred. | Myopia, or nearsightedness |
| occurs when objects are focused behind the retina and results in seeing distance objects clearly but close objects are blurred. | Hyperopia or farsightedness |
| the lens in the eye becomes progressively cloudy losing its normal transparency and thus altering the perception of images due to the interference of light transmission to the retina. | Cataract |
| Light adaptation occurs when we move from darkness into bright light. Retinal sensitivity _____ dramatically and the retinal neurons switch from the ____ to the ______ system. | decreases,rod, cone |
| Dark adaptation occurs when we go from a well-lit area into a dark one. The ____ stop functioning and the ____ starts to accumulate in the rods increasing retinal sensitivity. | cones, rhodopsin |
| Olfactory receptor cells are unique because they are one of the few types of neurons that undergo | mitosis |
| The organ of smell is the olfactory epithelium, which covers the_______ which contains olfactory receptor cells | superior nasal concha |
| 70% of all sensory receptors are in the | eye |
