Structures of the Ear
What is the role of the tympanic membrane?
Vibrates at the rate of sound waves in order to pass vibrations and information onto the ossicles (3 bones in ear)
Where is the auditory cortex located?
Temporal Lobe
What is the role of the outer ear?
Sound localization and funnels sound
The intensity of a soundwave
Amplitude
Measure of many waves occur
Frequency
What is the cochlea filled with?
Fluid and membranes with hair cells
Cells responsive to similar frequencies being located close to eachother is known as?
Tonotopic Map
How do we localize sound?
Time of arrival and differences in intensity
What part of the ear provides the opening for the cochlea?
Oval Window
What is the pinna made of?
Cartilage
Is the tympanic membrane found in the outer, middle, or inner ear?
Middle
Where do neural signals go after the auditory nerve?
Brainstem
What is the function of the ear canal?
Funnels sound toward the middle ear
Where can hair cells be found?
Basilar Membrane
Where does sound travel after the ear canal
Tympanic membrane
What is the role of the pinna?
Reflect sound into the ear
Where do neural signals go after the brainstem?
Thalamus
What is the role of the middle ear?
Amplify sound
What is amplitude measured in?
Decibels
Houses fluid and hair cells found on membranes
Cochlea
Hammer, Anvil, Stirrup
Where do neural signals go after the thalamus?
Auditory Cortex
What is the role of the inner ear?
Transition sound waves into neural signals
What is frequency measured in?
Hertz
What lobe is responsible for hearing?
Temporal Lobe
