External Ear
Sound waves enter through the auricle
They then travel through the external acoustic meatus
The sound waves then pass through and alter the pressure the tympanic membrane
Middle Ear
The vibrations of the tympanic membrane vibrate the auditory ossicles that are tiny bones
incus
The vibration then goes through the oval window
Fluids are transferred with in the vibrations that stimulate the hearing receptors
Malleus
stapes
Inner Ear
Scala Vestubuli helps conduct the sound vibrations to cochlear duct
The cochlear duct houses the organ of corti
Basilar membrane is a base for sensory cells of hearing(hair cells)
The organ of corti then releases neurotransmitters; which is the main organ of hearing
The tectorial membrane then bands the receptor hair s together
Scala tympani then allows vibrations to be released into tympanic cavity
The oval window then helps keep fluid moving within the cochlea and equalizes the pressure
The tympanic cavity then manages the air pressure b between the middle ear and external ear.
Pathway to brain
The cochlear nerve creates a nerve impulse that then Is transferred/sent to the brain
Then the vestibulocochlear and cochlear root merge together
The trunk of the vestibulocochlear nerve leaves the brain through the posterior canal fossa traveling lateral to the abducens nerve and facial nerve
