Q

Innermost layer where receptors for sense of sight are found
It is the nervous quote of the eyeball containing the photoreceptor cells

A

Retina

26
Q

Two types of photoreceptors

A

Rods and cones

27
Q

Stimulated by low intensity light for night vision and contains reddish pigment

A

Rods

28
Q

Stimulated by high intensity light for division or color vision photo pic sensitive to blue green and red lights

A

Cones

29
Q

Very sensitive and produces detectable signal on absorption of a single photon of light

A

Rhodopsin

30
Q

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

A

Refractive media of the eye

31
Q

Parts of the refractive media of the eye

A

Cornea
Aqueous humor
Lens
Vitreous humor

Q

A thin membrane separating outer from middle ear

A

Tympanic membrane or eardrum

37
Q

A small air filled cavity within the temporal bone

A

Middle ear

38
Q
