Q

what type of vision and light brightness causes dilator papillae (radial
muscles) to contract; pupils dilate

A

distant vision and dim light

24
Q

is distant or close vision sympathetic response?

A

distant vision

25
Q

is distant or close vision a parasympathetic response?

A

close vision

26
Q

The sensory layer of the eye consists of ???

A

the retina

27
Q

the retina is a delicate 2-layered membrane that absorbs ??? and prevents ??? and stores ???

A

light and prevents its
scattering and stores vitamin A

28
Q

the neural layer of the retina is a ??? that transduces light energy

A

photoreceptor

29
Q

TRUE or FALSE: the neural layer fo the retina contains bipolar cells, ganglion cells, amacrine
cells, and horizontal cells

A

TRUE these help with transmitting and processing signals

30
Q

the optic nerve turns into ??? in the retina

A

ganglion cells

31
Q

the rods in the eye operate in dim or bright light and provide indistinct, fuzzy, non-colour peripheral vision?

A

dim

32
Q

the cones in the eye operate in dim or bright light and provide high-acuity colour vision?

A

bright

33
Q

cones are concentrated in what part of the eye?

A

the fovea centralis and are found in the macula lutea

34
Q

rods in the eye are more numerous at peripheral region of the retina, away from the ???

A

macula lutea

35
Q

vitreous humour transmits ??? and holds the neural retina firmly against

A

transmits light and holds neural retina against pigmented layer

36
Q

which humour supplies nutrients and oxygen mainly to the lens and
cornea but also to the retina, and removes wastes

A

aqueous humour

37
Q

TRUE or FALSE: refraction is the Bending of a light ray due to change in speed when light passes from one transparent medium
to another

A

TRUE

38
Q

does refraction need to occur for distant vision?

A

only a very small amount, as light rays from distant objects are nearly parallel at
the eye and eye basically at rest

39
Q

for what type of vision must the eye make active adjustments?

A

close vision because light diverges at it gets closer to the eye

40
Q

high resolution vision is due to non-converging pathways in rods or cones?

A

cones

41
Q

what is the visual pigment of rods?

A

rhodopsin which is formed from vitamin A

42
Q

rhodopsin breaks down when ???

A

light enters the eye and is absorbed

43
Q

afferent impulses for hearing occurs in which part of what nerve?

A

the cochlear part of vestibulocochlear nerve

44
Q

afferent impulses for sense of balance occur in which part of what nerve?

A

the vestubular branch of vestibulocochlear

45
Q

what is the point of the auditory tube in the middle ear?

A

allows outside air in to equalise pressure

46
Q

what resppnds to gravity and changes in the position of the head in the ear?

A

the vestibule

47
Q

what is the vestibule?

A

it is a Central egg-shaped cavity of the bony labyrinth of semi circular canals

48
Q

semicircular canal receptors respond to what type of motion

A

rotational movements of the head

49
Q

where do sounds in the hearing range travel through?

A

through the cochlear duct, vibrating the basilar membrane at a specific location, according to the frequency of the sound

50
Q

what resonates in response to high-frequency pressure waves in the cochlea?

A

short, stiff fibres that span the width of the basilar membrane near oval window

51
Q

there is 1 row of inner hair cells
and 3 rows of outer hair cells in what part of the cochlea?

A

the spiral organ

52
Q

maculae in the ear respond to which type of movement: rotation or linear acceleration forces?

A

linear acceleration forces

53
Q

whereabouts can you find maculae that respond to vertical movement of head

A

saccule

54
Q

whereabouts can you find maculae that respond to horizontal movements and tilting the head side to side?

A

the utricle

55
Q

how is the crista ampularis activated?

A

Cristae respond to changes in velocity of
rotatory movements of the head
