- Soundwaves enter the outer ear (auditory canal) and strike the tympanic membrane (eardrum).
- Soundwaves vibrate off the eardrum and are transmitted by the ossicles to the oval window.
- These become fluid vibrations of the inner ear and are picked up by the mechanoreceptors, converted into an electrical impulse and sent to the brain for interpretation.

After the auditory ossicles, sound waves enter the cochlea, which is a spiral-shaped structure in the inner ear. Inside the cochlea, the sound waves are converted into electrical impulses by hair cells. These impulses are then transmitted to the brain via the auditory nerve, where they are processed and interpreted as sound.

What causes the auditory ossicles to vibrate?
The sound waves, coming through the auditory canal, strike the tympanic membrane (eardrum).The eardrum vibrates because of the soundwaves.This vibration is picked up by the ossicles and transmitted through the middle ear to the oval window.Therefore it is the soundwaves causing the eardrum to vibrate that ultimately makes the ossicles vibrate.

Do ossicles equalize pressure?
No, auditory ossicles amplify and transmit sound vibrations. The auditory tube is the place where the air pressure in the middle ear can be equalized by bringing air in from or out to the pharynx or throat.
What tube permits soundwaves to reach the eardrum?
The auditory canal allows sound to get to the eardrum.
Where are the ear bones or ossicles located?
The 3 auditory ossicles are "little bones" found in the middle ear. They are the smallest bones in the human body, and each one has its own name:· tympannic side = malleus or hammer· middle = incus or anvil· oval window side = stapes or stirrup

What is another medical term for auditory ossicle?
The term "ossicles" literally means "tiny bones" and commonly refers to the auditory ossicles, though the term may refer to any small bone throughout the body. The three auditory ossicles are the hammer, stirrup, and anvil.
What connects the tympanic membrane to the inner ear?
auditory ossicles
Do ossicles equalize pressure?
No, auditory ossicles amplify and transmit sound vibrations. The auditory tube is the place where the air pressure in the middle ear can be equalized by bringing air in from or out to the pharynx or throat.
What tube permits soundwaves to reach the eardrum?
The auditory canal allows sound to get to the eardrum.
What is fusion of the ossicles?
Fusion or fixation of the ossicles is where one or more of the three auditory ossicles cannot transmit sound vibrations for a variety of reasons. This does cause "conduction" deafness or hearing loss.
Consisting of the smallest bone?
Auditory ossicles of the ear are the smallest bones of the body.

because
The associated bones of the skull include what?
