Q

Rods and cones go to bipolar cells then to ganglion then to the optic nerve and sends info to the thalamus area called

A

Lateral geniculate nucleus

24
Q

The theory that says there are three types of cones: red blue and green. These three types of cones can make millions of combinations of colors. Does not explain after images or color blindness well.

A

Trichromatic theory

25
Q

The theory that sensory receptors come in pairs: red/green, yellow/blue, black/white. If one color is stimulated the other is inhibited.

A

Opponent process theory

26
Q

What feature of a sound wave gives us the amplitude of the sound

A

Height

27
Q

What feature of a sound wave gives us the pitch of the sound

A

Frequency

28
Q

What are the three Sections of the ear

A

Outer ear, middle ear, inner ear.

29
Q

Funnles sound into the ear hole

A

Outer ear

30
Q

Let’s sound waves enter the inner ear

A

Auditory canal

31
Q

Vibrates sound waves

A

Eardrum

32
Q

Three bones that vibrate sound

A

The occipital’s; hammer, anvil, stirrup

33
Q

Snail like part of the year that contains the mucous membrane with Celia that causes transduction

A

Cochlea

34
Q

Sound travels out of the ear through what

A

Auditory nerve, thalamus, temporal lobe

35
Q

Hairs vibrate in the Basilar membrane and turn vibrations into impulses called what

A

Organ of Corti

36
Q

Theory that different hairs vibrate in the cochlea when they hear different pitches. So some hairs vibrate when they hear high and others vibrate when they hear low.

A

Place theory

37
Q

The theory that all the hairs vibrate but at different speeds.

A

Frequency theory

38
Q

This kind of deafness happens when something goes wrong with the sound and vibration on the way to the cochlea. You can replace the bones or get a hearing aid..

A

Conduction deafness

39
Q

This kind of deafness occurs when the hair cells in the cochlea get damaged. Loud noises can cause this type of deafness. There’s no way to replace the hairs. Cochlear implant as possible.

A

Nerve deafness

40
Q

The theory that pain signals Encounter nerve gates that control whether the signals are allowed to pass through the brain. Melzac and Wall came up with this theory.

A

Gate control theory of pain

41
Q

What are the bumps on our tongue that Include taste buds on them

A

Papillae

42
Q

What are the four tastes

A

Sweet salty sour and bitter

43
Q

This tells us where our body is oriented in space. It controls our sense of balance. Is located in our semicircular Canal’s in our ears.

A

Vestibular sense

44
Q

Tells us where our body parts are. They are receptors located in our joints and muscles

A

Kinesthetic sense

45
Q

The ability to see objects in three dimensions despite their two dimensional representations on our retinas it’s called

A

Depth perception

46
Q

Any que that requires both eyes

A

Binocular

47
Q

The idea that the greater the difference between the images received by the two eyes, the nearer the object

A

Retinal disparity

48
Q

A que that requires one eye alone

A

Monocular

49
Q

If two objects are presumed to be the same size, the one that cast a smaller retinal image is perceived as further away. This is called

A

Relative size

50
Q

The idea that any object partially covered by another is seen as further away

A

Interposition

51
Q

The idea that objects lower in the visual field are seen as nearer

A

Relative height

52
Q

As we move, objects at different distances appear to move at different rates. This sensation is

A

Relative motion

53
Q

The idea that parallel lines appear to converge in the distance

A

Linear perspective

54
Q

The sensation that the dimmer of two objects seems further away

A

Light and shadow

55
Q

The stimulus for hearing

A

Audition
