Outer Ear
To collect sound.
What is a function of the outer ear?
To transmit acoustic energy from the tympanic membrane.
These structures house the necessary macula to detect horizontal and vertical acceleration.
What is the Ultricle and Saccule?
A collection of vibrations that travel through a medium and can be heard.
What is sound?
The ear is responsible for these two systems/mechanisms.

What is the pinna?
The malleus, incus, and stapes make up the ______.
What is ossicular chain?
These semicircular canals can sense movement of the head toward the shoulder.
What is tonotopic organization?
This transducer converts acoustic energy to electrochemical energy.
These three layers of tissue make up the tympanic membrane.
What is the curticular, fibrous, and mucous layers.
This structure is responsible for aeration and equalization of pressure of middle ear.
What is the Eustachian Tube?
It is used to allow communication between the ultricle and saccule
What is the endolymphatic duct?

What is an Auditory Brainstem Response?
Hungarian biophysicist that conducted research on the function of mammalian cochlea.
Who is Von Bekesy?
This structure acts as a handle to an inner ear structure.
What is the Manubrium?
Both these parts act as a protective mechanism by stiffening the ear to reduce vibrations that are received by the inner ear.
What is the tensor tympani and stapedius muscle?
Calcium Carbonate crystals inspire the category the saccule falls under.
What is a helicotrema?
This structure of the middle ear is 17 time smaller than the tympanic membrane.
