[ CH. 7 ] Auditory, the Body Senses, and the Chemical Senses

What are the three primary functions of audition (hearing)?

• Detect sounds

• Amplify vibrations

• Determine location of sources

• Determine identity of sources

What is pitch a measure of?

• Intensity of sound

• Complexity of sound

• Frequency of vibration

• Duration of sound

What does loudness measure?

• Complexity of sound

• Frequency of vibration

• Intensity of sound

• Duration of sound

Which of the following is the correct order of the ossicles in the middle ear from the tympanic membrane to the cochlea?

• Incus, Malleus, Stapes

• Malleus, Incus, Stapes

• Stapes, Incus, Malleus

• Incus, Stapes, Malleus

What is the function of the round window in the ear?

• It vibrates to amplify sound frequencies

• It permits sound vibrations to be transmitted into the fluid in the cochlea

• It serves as a shelf against which the cilia of the hair cells move

• It sustains auditory hair cells

What is the role of the Organ of Corti?

• It supports the auditory hair cells

• It is the cochlea's receptive organ and contains the sensory organ on the basilar membrane

• It is the membrane located above the basilar membrane and serves as a shelf

• It is the opening in bone surrounding the cochlea's inner ear

How many types of auditory hair cells are there?

• 1

• 2

• 3

• 4

What is the function of the tip links in cilia?

• They prevent noise-induced damage to the cochlea

• They attach the tip of one cilium to the side of the adjacent cilium

• They bundle moves toward the shortest cilium

• They secrete acetylcholine

Which part of the brain receives auditory information from the cochlear nerve?

• Cochlea

• Auditory cortex

• Vestibule

• Eustachian tube

What is the role of efferent fibers with the cochlear nerve?

• They send auditory information to the brain from the cochlea

• They secrete glutamate

• They prevent noise-induced damage to cochlea

• They attach the tip of one cilium to the side of the adjacent cilium
