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.
What is the function of the middle ear canal in the human auditory system?
The middle ear canal in the human auditory system helps to transmit sound vibrations from the outer ear to the inner ear. It also contains the three smallest bones in the body, known as the ossicles, which amplify and transmit these vibrations to the inner ear.
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 is the function of the ear canal structure in the human auditory system?
The ear canal in the human auditory system helps to collect sound waves and direct them to the eardrum, where they are converted into vibrations that can be processed by the inner ear.

The middle ear canal in the human auditory system helps to transmit sound vibrations from the outer ear to the inner ear. It also contains the three smallest bones in the body, known as the ossicles, which amplify and transmit these vibrations to the inner ear.
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.
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.
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?
In turning sound waves into vibrations and ultimately into electrical energy to be interpreted by the brain, these two structurs must transmit vibrations from the auditory canal to the fluid environment of the inner ear:tympanic membrane (eardrum)the three ossicles of the middle ear (malleus/incus/stapes)
What is the function of the ear canal structure in the human auditory system?
The ear canal in the human auditory system helps to collect sound waves and direct them to the eardrum, where they are converted into vibrations that can be processed by 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 (aka stirrup) is one of the three auditory ossicles of the middle ear. It presses up against the oval window to transmit sound vibrations into the fluid environment of the inner ear.
