What else can I help you with?
What structure separates the cochlear duct from the tympanic duct?
The basilar membrane separates the cochlear duct (scala media) from the tympanic duct (scala tympani) in the cochlea.
The cochlear duct relays vibrations to the auditory nerve fibers?
False
What area is found between the scala vestibuli and the scala tympany?
cochlear duct
What is the area found between the scala vestibuli and the scala tympani?
cochlear duct
How is the frequency of a sound indicated to the nervous system?
movement of the perilymph in the cochlear duct
What is the dividing line between the middle ear and the external ear?
The dividing line between the middle ear and the external ear is the tympanic membrane, also known as the eardrum. The tympanic membrane separates the outer ear canal from the middle ear cavity where the auditory ossicles are located.
Does the tympanic membrane separates the middle ear from the external ear?
Yes.
Which structure is a fluid-filled cavity that vibrates when sound waves strike it?
cochlear duct
Which thin membrane separates the outer and middle ear in tetrapods?
The ear drum. the medical term is the tympanic membrane
Does the cochlear duct relays vibrations to the auditory nerve fibers?
Yes, the cochlear duct contains sensory cells that convert vibrations into nerve signals. These nerve signals are then transmitted via the auditory nerve fibers to the brain for processing and perception of sound.
What membrane functions as an eardrum?
The tympanic membrane, also known as the eardrum, is a thin membrane that separates the outer ear from the middle ear. It plays a crucial role in transmitting sound vibrations from the outer ear to the middle ear.
What separates the external auditory meatus and middle ear?
The tympanic membrane (eardrum) separates the external auditory meatus (ear canal) from the middle ear. It vibrates in response to sound waves entering the ear canal and transmits these vibrations to the middle ear ossicles.
