2 Click on the each part of the ear To learn more QUESTION
3 The CochleaThe spiral cavity of the inner ear containing the organ of CortiThe cochlea produces nerve impulses in response to sound vibrationsGo back
4 The Cochlear NerveThe branch of the auditory nerve that connects with the cochlea and transmits impulses to the hearing center of the brainGo back
5 The Auricle The projecting, outer part of the ear The auricle is also known as the pinnaGo back
6 The Tympanic MembraneA membrane forming part of the organ of hearing, which vibrates in response to sound wavesThe tympanic membrane forms the eardrum, between the outer and middle earGo back
7 The 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 drumGo Back
8 The Incus One 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 earGo Back
9 The MalleusThe hammer-shaped bone that is the outermost of the three small bones in the mammalian middle earThe malleus can also be called the hammerGo back
10 The Stapes The innermost of the three small bones of the middle ear The stapes can also be called the stirrupGo back
11 The 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 tubeGo back
12 The Semicircular Canals The three looped fluid-filled membranous tubes, at right angles to one anotherThe semicircular canals control the senses of orientation and equilibriumGo back
13 QUESTIONWhich is located between the outer and middle ear, forming the eardrum?A. The CochleaB. The MalleusC. The Tympanic Membrane
14 Uh-Oh! Sorry, not the Cochlea! The Cochlea is located in the inner ear and responds to sound vibrations!TRY AGAIN!
15 Uh-Oh! Sorry, not the Malleus! The Malleus is the hammer shaped bone in the middle ear!Try again!
16 Good Job!!!Correct!The Tympanic Membrane is located between the outer ear and the middle ear, forming the ear drum!Continue
