47
Q

Eyeball layers:

A

Sclera
Choroid-
retina-

48
Q

Sclera

A

outer/ tough protective

49
Q

Cornea

A

Glassy transparent external surface of
the eye, allows light in eye
there’s water behind it

50
Q

choroid

A

middle layer, supplies blood to eye
-Iris: color, is what changes size of pupil
-Pupil: in center of iris controls light amount
- lens: behind iris focuses light into retina

51
Q

retina

A

innermost layer
-rods: active in dim luz, gray tone
-cones- bright and light, responsible for color vision

52
Q

optic nerve

A

bundle of axons from the retina, external image is transmitted to brain via optic nerve

53
Q

Eyelid

A

protects the eye
-eyelashes (cilia)
-sebaceous glands

54
Q

conjuctiva:

A

mucous membrane inside of eyelids, produces mucus and tears

55
Q

Lacrimal apparatus

A

produces tears
-Lacrimal ducts collect teas
-nasolacrimal duct drains into nasal cav

56
Q

Aqueous humor

A

Watery fluid between cornea and lens

57
Q

Vitreous humor

A

-semi solid gel between lens and retina

58
Q

Refraction is:

A

Bending of light when it enters a medium where its speed is different. (pencil in water cup; air fast medium-water slow)

59
Q

Ciliary body

A

pulls on edge of lens to accommodate to it can focus light (reading close)

60
Q

Vitreous humor

A

-semi solid gel between lens and retina

60
Q

Aqueous humor

A

Watery fluid between cornea and lens

61
Q

Ear responsible for:

A

hearing and equilibrium (semicircular canals and vestibular nerve 8)

62
Q

Auricle or pinna

A

actual oreja, gathers sound

63
Q

middle ear

A

transmits soundwaves to inner ear
-contains tiny bones: ossicles they amplify vibrations

64
Q

Inner ear

A

contains sensory receptors for equilibrium and hearing

65
Q

Aqueous humor

A

Watery fluid between cornea and lens

65
Q

Vitreous humor

A

-semi solid gel between lens and retina

66
Q

Aqueous humor

A

Watery fluid between cornea and lens

67
Q

Vitreous humor

A

-semi solid gel between lens and retina

68
Q

External ear

A

transmits soundwaves to middle ear

69
Q

External ear

A

transmits soundwaves to middle ear

69
Q

Aqueous humor

A

Watery fluid between cornea and lens

70
Q

Vitreous humor

A

-semi solid gel between lens and retina

71
Q

Aqueous humor

A

Watery fluid between cornea and lens

72
Q

External ear

A

transmits soundwaves to middle ear

72
Q

tympanic membrane:

A

eardrum

73
Q

ossicles 3:

A

Malleus
Incus
Stapes

73
Q

Eustachian tube

A

regulates pressure between mid ear and outside

73
Q

How we see:

A

Lights passes:
cornea,
pupil,
aqueous humor, lens,
vitreous humor,
Retina= stike cones and rods

74
Q

Vision requires 4 mechanisms

A
  1. Coordination of external eye muscles so both eyes move together
  2. Correct amount of light admitted by pupil
  3. Correct focus of light on retina by lens
  4. Optic nerve transmitting sensory images to brain
75
Q

Path of sound:

A

outer ear and middle ear and into cochlea of inner ear
- waves strike eardrum causing it to vibrate
-

76
Q

Cochlea

A

sound processing (hearing)

77
Q

Semicircular canals

A

angular or rotational acceleration
(are filled with fluid)

78
Q

nystagmus

A

involuntary eye movement

79
Q

Radiolucent:

A

Xrays go thru and image apears dark

80
Q

Radiopaque

A

xrays light dont pass thry so bones appear light in color

81
Q

strabismus

A

eye muscle weakness

82
Q

hordeolum

sty

83
Q

Ménière’s disease

A

Abnormal condition within the labyrinth of the inner ear that can lead to a
progressive loss of hearing
