Q

The sense of taste is classified as a

A

chemoreceptor

30
Q

The cells responsible for the sense of taste are the

A

gustatory cells

31
Q

The six primary taste sensations are

A

sweet, salty, metallic, bitter, sour, umami

32
Q

The sense of smell is classified as

A

a chemoreceptor

33
Q

The olfactory receptors

A

also assist in the sense of taste

34
Q

The sense of smell is

A
  • sensitive
  • easily adapted
  • can respond to chemicals dissolved in water
35
Q

The sense of smell is able to stimulate vivid memories because the olfactory tract passes
through the

A

limbic

36
Q

Which of the following sensations is generated by a general sense organ?

A

Touch

37
Q

Which of the following sensations is generated by a special sense?

A

Taste

38
Q

Which of the following is not considered one of the layers of the eye?

A

Iris

39
Q

Which of the following is not part of the vascular layer of the eye?

A

Cornea

40
Q

Which of the following is not true about the senses of taste and smell?

A

Both respond to six primary stimuli

41
Q

The vestibular nerve contains a nerve from the

A
  • semicircular canals
  • vestibule
42
Q

Which sensation is not sensed by a general sense organ?

A

Equilibrium

43
Q

Which sensation is sensed by a special sense organ?

A
  • Smell
  • Equilibrium
  • Taste
44
Q

Which of the following is not true of a general sense organ?

A

They are grouped in a localized area

45
Q

This is a functional characteristic of all sense organs

A
  • must be able to detect a stimulus
    -must be able to detect a change in the intensity of the stimulus
  • must be able to change the stimulus into a nerve impulse
46
Q

A condition where the lens of the eye becomes milky in appearance and loses its transparency
is called

A

a cataract

47
Q

An infection of the middle ear is called

A

otitis media

48
Q

An increase in pressure inside the eye is called

A

glaucoma

49
Q

The ‘‘farsightedness’’ of old age is called

A

presbyopia

50
Q

Which of the following is part of the sensory pathway of all sense organs?

A
  • Able to sense or detect a stimulus
  • Detection of a stimulus is converted to a nerve impulse
  • Signal from nerve impulse is conducted to the brain
  • Processing information is the sensation perceived in the brain
51
Q

Why are the many unique flavors we recognize not just tastes alone but a combination of
sensations based on tastes, odors, touch, temperature, and pain?

A

All incoming signals are integrated with other sensory signals and even memories
to produce our perceptions.
