Taste

2

The chemical sense of olfaction corresponds to? 

Smell

3

The chemoreceptors of the chemical senses respond to chemicals in aqueous solution. What substance does taste dissolve in?  

To substances dissolved in saliva 

4

The chemoreceptors of the chemical senses respond to chemicals in aqueous solution. What substance does smell dissolve in? 

To substances dissolved in fluids of the nasal

membranes 

5

10,000+

6

Where are taste buds found on the tongue?

Taste buds are found in papillae of the tongue mucosa

14

What are the five basic taste sensations? 

  1. Sweet
  2. Salt
  3. Sour
  4. Bitter
  5. Umami (savory) 

15

What correlates with sweet? 

Sugars, saccharin, alcohol, and some amino acids 

16

What correlates with salt? 

Metal ions

17

What correlates to sour? 

Hydrogen ions 

18

What correlates to bitter? 

Alkaloids such as quinine and nicotine

19

What correlates to umami (savory)? 

Elicited by the amino acid glutamate

20

What are the influences of other sensations on taste? 

  • Thermoreceptors, mechanoreceptors, nociceptors also influence taste
  • Temperature and texture enhance or detract from taste 

21

What is the organ of smell? 

The organ of smell is the olfactory epithelium 

22

Where is the organ of smell located? 

The olfactory epithelium covers the superior nasal concha

23

What are olfactory receptor cells? 

Bipolar neurons with radiating olfactory cilia

24

What surrounds/cushions olfactory receptor cells? 

Supporting cells 

25

What are the three parts of the ear? 

  1. Inner ear
  2. Middle ear
  3. Outer ear

26

What parts of the ear of involved with hearing? 

Outer and middle ear

27

What is the function(s) of the inner ear? 

Hearing & equilibrium 

28

Characteristics of the receptors for hearing and balance

  • Respond to separate stimuli
  • Are activated independently 

29

The auricle (pinna) is composed of? 

The lobule (earlobe) 

30

Characteristics of the external auditory canal

  • Short
  • Curved tube
  • Filled with ceruminous glands
