External Ear image

Sound waves enter through the auricle image

They then travel through the external acoustic meatus image

The sound waves then pass through and alter the pressure the tympanic membrane image

Middle Ear image

The vibrations of the tympanic membrane vibrate the auditory ossicles that are tiny bones image

incus image

Malleus image

stapes image

The vibration then goes through the oval window image

Fluids are transferred with in the vibrations that stimulate the hearing receptors image

Inner Ear image

Scala Vestubuli helps conduct the sound vibrations to cochlear duct image

The cochlear duct houses the organ of corti image

Basilar membrane is a base for sensory cells of hearing(hair cells) image

The organ of corti then releases neurotransmitters; which is the main organ of hearing image

The tectorial membrane then bands the receptor hair s together image

Scala tympani then allows vibrations to be released into tympanic cavity image

The oval window then helps keep fluid moving within the cochlea and equalizes the pressure image

The tympanic cavity then manages the air pressure b between the middle ear and external ear. image

Pathway to brain image

The cochlear nerve creates a nerve impulse that then Is transferred/sent to the brain image

Then the vestibulocochlear and cochlear root merge together image

The trunk of the vestibulocochlear nerve leaves the brain through the posterior canal fossa traveling lateral to the abducens nerve and facial nerve image
