25
Innermost layer where receptors for sense of sight are found It is the nervous quote of the eyeball containing the photoreceptor cells
Retina
26
Two types of photoreceptors
Rods and cones
27
Stimulated by low intensity light for night vision and contains reddish pigment
Rods
28
Stimulated by high intensity light for division or color vision photo pic sensitive to blue green and red lights
Cones
29
Very sensitive and produces detectable signal on absorption of a single photon of light
Rhodopsin
30
The transparent structures traverse by the light race on the way to the photoreceptors of the retina This structures can bend or refract the light rays so the images can be focused on the retina
Refractive media of the eye
31
Parts of the refractive media of the eye
Cornea Aqueous humor Lens Vitreous humor
32
Parts of the external ear
Pinna or auricle External acoustic meatus
33
Middle ear is also called as
Tympanic cavity
34
Shell shaped structure surrounding the auditory canal opening
Pinna or auricle
35
Short narrow chamber about one it's long by 1/2 in wide Curve into temporal bone of the skull Skin of wolves line with ceremonious glands with secret a waxy yellow substance called ear wax or cerum
External auditory canal
36
A thin membrane separating outer from middle ear
Tympanic membrane or eardrum
37
A small air filled cavity within the temporal bone
Middle ear
38
A bony wall with two openings oval window and around window
Medial boundary
39
Tympanic membrane with handle of the malleus attached
Lateral boundary
40
Eustachian tube which connects middle ear and nasopharynx
Anterior boundary
41
Mastoid process
Posterior boundary
42
Ossicles in the middle ear:
Malleus or hammer Incus or anvil Stapes or stirrups
43
An ossicle in the middle ear That is attached to tympanic membrane
Malleus or hammer
44
Ossicles In the middle ear the presses on the oval window of the inner ear
Stapes or stirrups
45
Internal ear or inner ear is composed of two parts
Bony labyrinth Membranous labyrinth
46
What is the fluid inside the bony labyrinth
Perilymph
47
Three parts of the bony labyrinth
Cochlea Vestibule Three semicircular canals
48
Made up of scala vestibuli and timpani which is concerned with hearing
Cochlea
49
Concerned with static equilibrium
Vestibule
50
Concerned with dynamic equilibrium
Three semic circular canals
51
It is found inside the bony labyrinth which has a fibrous wall
Membranous labyrinth
52
It is the fluid inside the membranous labyrinth
Endolymph
53
Three parts under the membranous labyrinth
Scala media Utricle and saccule Three semicircular ducts
54
Inside the bony cochlea
Scala media
55
Inside bony vestibule
Utricle and saccule
56
Inside the send me circular canal
Three semicircular ducts
57
Receptor for hearing
