The Auditory system

Your eardrum is also known as the:

• Tympanic Membrane
• Tempanic Membrane
• Timpanic Membrane
• Tompanic Membrane

What happens to the eardrum when sound hits, causing transmission of sound to the inner ear?

• it opens
• it grows hair
• it refracts the sound
• it vibrates

Which part of ear provides equilibrium?

• cochlea

• oval window

• semicircular canals

• ossicles

What part of the ear sends signals to the brain?

• optic nerve
• ear canal
• auditory nerve
• middle ear

Which part of the ear is shaped like a snail shell?

• eardrum
• auditory nerve
• cochlea
• anvil

The position on the basilar membrane at which waves reach their peak depends on the frequency of a tone.  Accounts for high pitched sounds. 

• place theory
• frequency theory
• binocular depth cues

Which part of the ear acts as the sound collector?

• outer ear
• ear canal
• middle ear
• inner ear

The rate of the neural impulses traveling up the auditory nerve matches the frequency of a tone. 

• place theory
• frequency theory
• Weber's law

What is unique about the hammer, stirrup, and anvil?

• They are the smallest bones in your body

• They are the only bones in your body that move

• They are the only bones located in your head

• They are the only bones that cannot be broken

Place the following events in sequence: A) Your eardrum begins vibrating; B) Electrical impulses travel along nerve fibers; C) The hammer, anvil, and stirrup begin moving
