Q

Job of oval window

A

Collects and transfer sound vibrations from ossicles to the cochleaJ

22
Q

Job of eustachian tube

A

Balances the air pressure on both sides of the eardum

23
Q

Job of cochlea

A

Detects and converts sound vibration into nerve impulses

24
Q

Job of Semicircular canals

A

Detects the positions of the head and help to balance the body

25
Q

Job of Auditory nerve

A

Send nerve impulses from the cochlea to the brain to be interpreted

26
Q

What are smells?

A

Chemical subtances present in the air

27
Q

What is the fucntion of sensory cells for smell?

A

Sensory cells for smell are tiny and covered with a layer of mucus. Chemical substances in the air will dissolve in this layer of mucus and stimulate cells to produce nerve impulses to the brain to be interpreted

28
Q

What are the tiny nodules on the tongue known as?

A

Papillae

29
Q

what are the papillae covered in?

A

Taste buds

30
Q

Function of taste buds?

A

when food is chewed, chemical substances in food dissolve in saliva and diffuse into the taste buds to stimulate taste receptors and produce nerve impulses

31
Q

Types of receptors in the skin?

A

Pain, cold, heat, touch and pressure receptor`

32
Q

How does the skin function?

A

when receptors on the skin are stimulated, nerve impulses are produced and sent through the nervous system to be interpreted

33
Q

mechanism of hearing

A

Earlobe, ear canal, eardrum, ossicles, oval window, cochlea, auditory nerve, brain

34
Q

Examples of limitations of sigh

A

Optical Illusions and blind spots

35
Q

How does an optical illusion occur?

A

when an object seen differs from its actual state

36
Q

what causes astigmatism?

A

Caused by the uneven curvature of the cornea and eye lens

37
Q

How to correct astigmatism

A

Cylindrical Lenses

38
Q

What causes short sightedness?

A

Eye lens too thick or eye ball too long

39
Q

How to correct short sightedness?

A

Concave lenses

40
Q

What causes long sightedness?

A

Eye lens too thin or eye ball too short

41
Q

How to fix long sightedness?

A

Convex lens

42
Q

Frequency of human ears?

A

20 - 20000 Hz

43
Q

How does age affect the frequency range of hearing?

A

The older the person, the lower the frequency range of the person

44
Q

How does loudspeaker work?

A

Amplifies sound to be heard from far away

45
Q

What are examples of responses in plants?

A

Tropism and Nastic Movement

46
Q

What is tropism

A

Directional response of plants to stimuli

47
Q

Examples of tropism

A

Geotropism
Hydrotropism
Phototropism
Thigmotropism

48
Q

What is nastic movement

A

Response towards a stimulus but does not depend on the direction of the stimulus

49
Q

What is stereophonic hearing

A

Hearing using both ears

50
Q

Importance of stereophonic hearing

A

Determine location of a source of sound
