What kind of physical stimuli is necessary for smell to work?
Olfactory sense: (chemical: smell) = olfactory epithelium - superior nasal concha - nasal passage
30

Gravity (inertia: acceleration/position) hair cells in maculae in the utricles/saccules (inner ear)
33
What kind of physical stimuli is necessary for acceleration/position to work?
Gravity (inertia: acceleration/position) hair cells in maculae in the utricles/saccules (inner ear)
34
What is the function of the conchea/meati in the passage?
increases the surface area in the nasal cavity and prevents dehydration
35
What are the 3 types of epithelium that cover the 3 nasal passage?
superior nasal conchae - olfactory epithelium
middle nasal conchae - respitory epithelium
inferior nasal conchae - (easily broken) - respitory epithelium
36
Trace the passage of tears from the lacrimal gland to the nostrils
lacrimal gland --- lacrimal duct --- conjuctiva -lacrimal caruncle --- lacrimal puncta --- Lacrimal canliculi --- nasolacrimal sac --- nasolacrimal duct --- nasal meatus --- Nasal cavity
37
What structures are involved when vibration (sound) is transfered from the tympatic membrane to the cochlea?
Tympatic membrane - malleus, incus, stapes, oval window cochlea, round window
38
function of the stapedius muscle
- decrease sensitivity of hearing
- dampens large vibrations of stapes
- protect oval window
39
Function of the Tensor tympani muscle?
- Limits movement
| - increases tension on eardrum to prevent damage to inner ear from loud noises
40
