External Ear
Collects & directs sound waves into the external acoustic meats.
What is Auricle(pinna)?
Transmits & amplifies vibrations from the tympanic membrane.
What is the malleus(hammer)?
Hearing
What is the Cochla?
Transmits sound waves from the auricle to the tympanic membrane.
What is the External acoustic meatus?
Transmits & amplifies vibrations from the malleus to the stapes.
Equilibrium static equilibrium & linear acceleration of the head.
Vestibule
Vibrates at exactly the same frequency as the sound wave(s) hitting it & transmits vibrations to the auditory ossicle.
What it the tympanic membrane?
Transmits & amplifies vibrations from the incus to the oval window.
What is the stapes (Sirrup)?
equilibrium rotational acceleration of the head
What is the Semicircular canals?
Completes the formation of the auricle.
What is the lobule(earlobe)?
Transmits vibrations from the stapes to the perilymph of the scala vestibule.
What is the Oval Window?
Equalizes the pressure in the middle ear cavity with external air pressure so that the tympanic membrane can Vibrate properly.
Wha is the pharygotympanic (auditory) tube?
