Ear 👂🏼

The perceived pitch of a sound depends on

• A) vibrations of the tympanic membrane being transmitted through the incus.

• B) vibrations of the oval window creating wave formation in the fluid of the vestibular

  canal.

• C) the region of the basilar membrane where the signal originated.

• D) A and C only

Which of the following is an attachment site between sensory hairs that open ion channels

when the hairs bend?

• tip links

• statoliths

• otoliths

• Round window

Which of the following contains mechanoreceptors that react to low frequency waves in

much the same manner as our inner ear?

• our sense of taste

• pain receptors

• lateral line systems

• receptors for light touch

Which structure(s) is (are) involved in equalizing the pressure between the ear and the

atmosphere?

• A) 1 and 8

• B) 5 and 7

• C) 8

• D) 9

What are sensillae?

• smell receptors in animals with hydrostatic skeletons

• mechanoreceptors that help birds remain oriented during fligh

• specific type of hair cell in the human ear

• insect taste receptors found on feet and mouthparts

) If a stimulus is to be perceived by the nervous system, which part of the sensory pathway

must occur first?

• integration

• transmission

• reception

• amplification

What is the correct sequence of events that would lead to a person hearing a sound?

1. transmission

2. transduction

3. integration

4. amplification

• 2, 4, 1, 3

• 3, 1, 2, 4

• 1, 2, 3, 4

• 3, 1, 4, 2

Which of the following receptors is incorrectly paired with the type of energy it transduces?

• mechanoreceptors-sound

• pain receptors-electricity

• chemoreceptors-solute concentrations

• thermoreceptors-heat

What do hearing, touch, and a full stomach have in common?

• The transducers are all proprioceptors.

• The sensory information from all three is sent to the thalamus.

• The sensory receptors are all hair cells.

• Electrical energy is transduced to form an action potential.
