The CochleaThe spiral cavity of the inner ear containing the organ of Corti
The cochlea produces nerve impulses in response to sound vibrations
Go backThe Cochlear NerveThe branch of the auditory nerve that connects with the cochlea and transmits impulses to the hearing center of the brain
Go backThe Auricle The projecting, outer part of the ear
The auricle is also known as the pinna
Go backThe Tympanic Membrane A membrane forming part of the organ of hearing, which vibrates in response to sound waves
The tympanic membrane forms the eardrum, between the outer and middle ear
Go backThe External MeatusThe external meatus is a tube running from the outer ear to the middle ear. The human ear canal extends from the pinna to the eardrum and is about 26 mm in length and 7 mm in diameterThe external meatus is also known as the ear drum
Go BackThe IncusOne of the three tiny bones in the middle ear Sound impulses coming from the eardrum are conveyed from the malleus to the incus and from the incus to the stapes at the oval window to the inner ear
Go BackThe MalleusThe hammer-shaped bone that is the outermost of the three small bones in the mammalian middle ear
The malleus can also be called the hammer
Go backThe StapesThe innermost of the three small bones of the middle ear
The stapes can also be called the stirrup
Go backThe Auditory TubeThe tube that runs from the middle ear to the pharynxThe function of this tube is to protect and drain the middle earCan also be known as the Eustachian tube
Go backThe Semicircular Canals The three looped fluid-filled membranous tubes, at right angles to one another
The semicircular canals control the senses of orientation and equilibrium
Go backQUESTIONWhich is located between the outer and middle ear, forming the eardrum?
A. The CochleaB. The MalleusC. The Tympanic Membrane
