47
Eyeball layers:
Sclera
Choroid-
retina-
48
Sclera
outer/ tough protective
49
Cornea
Glassy transparent external surface of
the eye, allows light in eye
*there's water behind it*
50
choroid
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
retina
innermost layer
-rods: active in dim luz, gray tone
-cones- bright and light, responsible for color vision
52
optic nerve
bundle of axons from the retina, external image is transmitted to brain via optic nerve
53
Eyelid
protects the eye
-eyelashes (cilia)
-sebaceous glands
54
conjuctiva:
mucous membrane inside of eyelids, produces mucus and tears
55
Lacrimal apparatus
produces tears
-Lacrimal ducts collect teas
-nasolacrimal duct drains into nasal cav
56
Aqueous humor
Watery fluid between cornea and lens
57
Vitreous humor
-semi solid gel between lens and retina
58
Refraction is:
Bending of light when it enters a medium where its speed is different. (pencil in water cup; air fast medium-water slow)
59
Ciliary body
pulls on edge of lens to accommodate to it can focus light (reading close)
60
Vitreous humor
-semi solid gel between lens and retina
60
Aqueous humor
Watery fluid between cornea and lens
61
Ear responsible for:
hearing and equilibrium (semicircular canals and vestibular nerve 8)
62
Auricle or pinna
actual oreja, gathers sound
63
middle ear
transmits soundwaves to inner ear
-contains tiny bones: ossicles they amplify vibrations
64
Inner ear
contains sensory receptors for equilibrium and hearing
65
Aqueous humor
Watery fluid between cornea and lens
65
Vitreous humor
-semi solid gel between lens and retina
66
Aqueous humor
Watery fluid between cornea and lens
67
Vitreous humor
-semi solid gel between lens and retina
68
External ear
transmits soundwaves to middle ear
69
External ear
transmits soundwaves to middle ear
69
Aqueous humor
Watery fluid between cornea and lens
70
Vitreous humor
-semi solid gel between lens and retina
71
Aqueous humor
Watery fluid between cornea and lens
72
External ear
transmits soundwaves to middle ear
72
tympanic membrane:
eardrum
73
ossicles 3:
Malleus
Incus
Stapes
73
Eustachian tube
regulates pressure between mid ear and outside
73
How we see:
Lights passes:
cornea,
pupil,
aqueous humor, lens,
vitreous humor,
Retina= stike cones and rods
74
Vision requires 4 mechanisms
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
Path of sound:
outer ear and middle ear and into cochlea of inner ear
- waves strike eardrum causing it to vibrate
-
76
Cochlea
sound processing (hearing)
77
Semicircular canals
angular or rotational acceleration
(are filled with fluid)
78
nystagmus
involuntary eye movement
79
Radiolucent:
Xrays go thru and image apears dark
80
Radiopaque
xrays light dont pass thry so bones appear light in color
81
strabismus
eye muscle weakness
82
hordeolum
sty
83
Ménière’s disease
Abnormal condition within the labyrinth of the inner ear that can lead to a
progressive loss of hearing
