Q

What kind of physical stimuli is necessary for smell to work?

A

Olfactory sense: (chemical: smell) = olfactory epithelium - superior nasal concha - nasal passage

30
Q

What kind of physical stimuli is necessary for taste to work?

A

Gustatory sense: (chemical: taste) gustory cells in taste buds (dorsum of tounge)

31
Q

What kind of physical stimuli is necessary for vision to work?

A

Visual sense (electromagnetic radiation: vision) - Rods and Cones in retina of eye

32
Q

What kind of physical stimuli is necessary for movement/balance to work?

A

Equilibrium (Inertia: movement/balance) hair cells in crista in semicircular canals (inner ear)

33
Q

What kind of physical stimuli is necessary for acceleration/position to work?

A

Gravity (inertia: acceleration/position) hair cells in maculae in the utricles/saccules (inner ear)

33
Q

What kind of physical stimuli is necessary for acceleration/position to work?

A

Gravity (inertia: acceleration/position) hair cells in maculae in the utricles/saccules (inner ear)

34
Q

What is the function of the conchea/meati in the passage?

A

increases the surface area in the nasal cavity and prevents dehydration

35
Q

What are the 3 types of epithelium that cover the 3 nasal passage?

A

superior nasal conchae - olfactory epithelium
middle nasal conchae - respitory epithelium
inferior nasal conchae - (easily broken) - respitory epithelium

36
Q

Trace the passage of tears from the lacrimal gland to the nostrils

A

lacrimal gland — lacrimal duct — conjuctiva -lacrimal caruncle — lacrimal puncta — Lacrimal canliculi — nasolacrimal sac — nasolacrimal duct — nasal meatus — Nasal cavity

37
Q

What structures are involved when vibration (sound) is transfered from the tympatic membrane to the cochlea?

A

Tympatic membrane - malleus, incus, stapes, oval window cochlea, round window

38
Q

function of the stapedius muscle

A
  • decrease sensitivity of hearing
  • dampens large vibrations of stapes
  • protect oval window
39
Q

Function of the Tensor tympani muscle?

A
  • Limits movement

- increases tension on eardrum to prevent damage to inner ear from loud noises

40
Q

What is the function of Pinna?

A

Collects sound waves

41
Q

48
Q

What is the function of the superior oblique and the CN?

A

moves eye inferior/aBduction ( depresses and lateral)

- trochlear

49
Q

What is the function of the inferior oblique and the CN?

A

moves eye Superior/aBduction ( elevates and lateral)

50
Q

What are the 3 layers of the eye?

A

Fibrous tunic / layer
Vascular tunic/ layer
Neural tunic/ layer

51
Q

What is the function of the fibrous tunic of the eye?

A
  • mechanical support
  • physical protection
  • attachment site for occulomotor
  • contains focusing process
51
Q

What is the function of the Vascular tunic of the eye?

A

Provide route for blood and lymphatic supplying tissues

  • regulating light entering
  • secreting and absorbing aqueous humor
  • controlling the shape of the lens
52
Q

What is the function of the neural tunic of the eye?

A
  • photorecepters that respond to light
  • supporting cells and neurons that perform preliminary processing
  • intergrating of visual info
  • blood vessels that supply the tissues lining the posterior cavity
