What is the function of the auditory tubes?
The main function of the eustachian tube is ventilation of the middle ear and maintenance of equalized air pressure on both sides of the tympanic membrane (eardrum). Closed at most times, the tube opens during swallowing. This permits equalization of the pressure without conscious effort.
What is the function of the auditory tube quizlet?
The function of the auditory tube is to equalize the pressure of the middle ear and the outside air, so the ear bones can vibrate.
What is the auditory tube called?
Eustachian tube
The Eustachian tube is a small passageway that connects your throat to your middle ear. When you sneeze, swallow, or yawn, your Eustachian tubes open. This keeps air pressure and fluid from building up inside your ear. But sometimes a Eustachian tube might get plugged.
What are 3 functions of the Eustachian tube?
The Eustachian tube has three primary functions: 1) ventilation of the middle ear so that ambient pressure and middle ear pressure are similar; 2) protection of the middle ear from reflux of nasopharyngeal secretions and bacterial flora; and 3) drainage of secretions from the middle ear into the nasopharynx.
What is the purpose of the auditory tubes open into the nasopharynx?
Auditory tubes open into the nasopharynx to allow for air to pass between the nasopharynx and the parts of the ear behind the eardrum.
What is the function of the auditory ossicles?
The function of the tympanic membrane and the auditory ossicles is to transmit and amplify sound and to convert sound waves into pressure waves in the perilymph and endolymph.
What are functions of the auditory ossicles?
What are the functions of auditory ossicles quizlet?
The function of the ossicles is to transmit the vibratory motion of the eardrum to the oval window. In sequence, the tympanic membrane vibrations are transferred to the malleus, then the incus, and finally the stapes.
What does the auditory nerve do?
The cochlear nerve, also known as the acoustic nerve, is the sensory nerve that transfers auditory information from the cochlea (auditory area of the inner ear) to the brain. It is one of the many pieces that make up the auditory system, which enables effective hearing.
What is the function of the auditory nerve?

What is the purpose of the auditory tubes open into the nasopharynx quizlet?
TestNew stuff! Why do the auditory tubes open into the nasopharynx? The auditory tube allows air to pass between the cavity of the middle ear and the outside environment. As a result, air pressure normally remains equal on both sides of the eardrum.
What is the function of the internal auditory canal?
The external auditory canal is the only skin lined cul-de-sac in the whole human body. It is known to perform both auditory and non auditory functions. The auditory function is that it permits efficient sound transmission from the environment to the tympanic membrane, self maintenance of a clear passage for transmission of sound.
What does the auditory tube do in your ear?
Auditory tube: The tube that runs from the middle ear to the pharynx, also known as the Eustachian tube . The function of this tube is to protect, aerate and drain the middle ear (and mastoid). Occlusion of the Eustachian tube leads to the development of middle ear inflammation ( otitis media ).
What is the purpose of auditory tubes opening into nasopharynx?
Nasopharynx. The auditory tube, which connect the middle ear to the pharynx, opens into the nasopharynx at the pharyngeal opening of the auditory tube. The opening and closing of the auditory tubes serves to equalize the barometric pressure in the middle ear with that of the ambient atmosphere.
What is auditory tube called?
Auditory Tube Anatomy. The auditory tube,sometimes called the eustachian tube,is a tiny channel that runs from the middle ear to the back of the throat (nasopharynx).
