Best Answer

The external auditory canal collects sound waves and funnels them towards the eardrum. The eardrum vibrates in response to the sound waves, which then transmit the vibrations to the three small bones in the middle ear. These bones amplify the vibrations and send them to the cochlea in the inner ear, where they are converted into electrical signals that are sent to the brain for interpretation.

What does the external auditory canal do?

The external auditory canal, also known as the ear canal, serves to transmit sound waves from the environment to the eardrum. It is responsible for protecting the middle and inner ear structures from foreign objects and damage. Its curved shape also helps amplify and filter sound waves before they reach the eardrum.


Receives sounds and sends them through the auditory canal to the eardrum?

Sounds are received by the outer ear (pinna) and travel through the auditory canal to reach the eardrum (tympanic membrane). The vibrations of the eardrum then set the middle ear bones in motion, which transmit the sound to the inner ear for further processing.


Structure composing external ear?

The external ear is composed of two main structures: the pinna (auricle) and the external auditory canal. The pinna is the visible part of the ear that helps collect and direct sound waves towards the ear canal. The ear canal is a tube-like structure that extends from the pinna to the eardrum, and it is lined with skin and fine hairs to help trap debris and protect the ear.


What does auditory canal mean?

The auditory canal is a tube-like structure in the ear that carries sound waves from the pinna (outer ear) to the eardrum. It also helps protect the delicate structures of the middle and inner ear from damage.


What transmits sound from the inner ear to the brain?

The auditory nerve transmits sound signals from the inner ear to the brain. It carries electrical impulses generated by the hair cells in the cochlea to the brainstem, where the signals are further processed and interpreted as sound.

What is a widely patent auditory canal?

The auditory canal is your inner ear - the part inside your cranium. Patent means open. A widely patent auditory canal would be one that is especially wide/open/large.

What is the word for definition 'inner end of the auditory canal?

I believe the answer is the ear drum.


Sounds entering the external auditory canal are eventually converted to nerve impulses via a chain of events?

Yes, sound waves travel through the external auditory canal and cause the eardrum to vibrate. These vibrations are then transmitted through the middle ear bones to the inner ear, where they stimulate hair cells in the cochlea. The hair cells convert the vibrations into electrical signals that are sent to the brain via the auditory nerve.

What two structures transmit vibrations from the external auditory canal to the inner ear fluid?

The two structures are the ossicles (specifically the malleus, incus, and stapes) and the oval window. The ossicles amplify and transmit sound waves from the eardrum to the oval window, which then sends the vibrations into the fluid-filled cochlea of the inner ear.


What does the auditory canal do for the ear?

Basically, the auditory canal links the outer ear to the ear drum. It carries the vibrations from outer ear to the inner ear.


How does the external ear work?

The external ear acts as a funnel to collect sound waves and direct them towards the middle ear. The shape and structure of the external ear help to amplify and localize sounds, while also providing protection for the delicate structures of the middle and inner ear. Sound waves enter the ear canal, causing the eardrum to vibrate and transmit these vibrations to the middle ear ossicles, which then amplify and transmit the sound further into the inner ear for processing.


What does the stapes or stirrup press against?

The stapes or stirrup in the middle ear presses against the oval window, which is a membrane that separates the middle ear from the inner ear. This transfer of vibrations helps to transmit sound from the ear canal to the cochlea in the inner ear.


What is the boundary between the middle and inner ear?

The boundary between the middle and inner ear is marked by the oval window and round window. The oval window connects the middle ear to the inner ear via the stapes bone, while the round window helps dissipate sound waves within the inner ear.


Does the auditory canal carry the message of sound to the brain?

No, the auditory canal simply serves to channel sound waves to the middle ear. Once in the middle ear, the sound waves are converted into vibrations that travel through the ossicles to the inner ear, where they are converted into electrical signals that are then sent to the brain via the auditory nerve.
