Alkaloids such as quinine and nicotine

19

What correlates to umami (savory)? 

Q image thumb

Elicited by the amino acid glutamate

20

What are the influences of other sensations on taste? 

Q image thumb

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

21

28

Characteristics of the receptors for hearing and balance

Q image thumb

  • Respond to separate stimuli
  • Are activated independently

  • Transfers sound energy to the middle ear ossicles
  • Boundary between the outer and middle ears 

32

Characterisitcs of the Middle Ear (Tympanic Cavity)

Q image thumb

  • A small, air-filled, mucosa-line cavity
    • Flanked laterally by the eardrum
    • Flanked medially by the oval and round windows 

33

Characteristics of the Eustachian tube

Q image thumb

  • Also known as the auditory tube
  • Connects the middle ear to the nasopharynx
