What causes the hair cells to trigger the neurons to send a signal?1 The tympanic membrane vibrating with sound waves. The tectorial membrane rubbing against them. The vibrations in the fluid moving the hairs. The efferent nerves fibers bringing in signals from the brain. Both the middle ear and inner ear are filled with fluid.1 True False Which of these is NOT a part of the organ of Corti?1 hair cells nerve cells tectorial membrane tympanic membrane Where is the end of the Eustachian tube?1 in the larynx inside the sinuses in the inner ear in the nasopharynx Which of these is involved with our sense of balance?1 organ of Corti middle ear cochlea vestibular system The entire outer ear (the part we see) is correctly called the:1 tragus pinna frenulum helix Which of these describes the hearing range of humans?1 2,000 Hz to 200,000 Hz 20 Hz to 200 Hz 2 Hz to 20 Hz 20 Hz to 20,000 Hz Which of these words accurately describes the eardrum?1 translucent opaque transparent Which of these ensures equal pressure on both sides of the eardrum?1 malleus Eustachian tube oval window vestibule auditory canal Which of these touches the stirrip (stapes)?1 oval window round window Which of these touches the eardrum?1 oval window anvil hammer stirrup Which of these is the smallest bone in the body?1 malleus (hammer) stapes (stirrup) incus (anvil) Which one of these is NOT part of the inner ear?1 semicircular canals vestibule cochlea round window stapes How many semicircular canals are in the vestibular system?1 1 3 4 2 The shape of the pinna helps to bring in sound, especially the frequencies of the human voice.1 True False Where does the word “cochlea” come from?1 Greek for "cone-shaped." Greek for "tube." Latin for "complicated maze." Greek for "snail shell." Latin for "hammer." What is the function of the middle ear?1 to translate sound into electrical signals to transfer sound vibrations to the inner ear to give us a sense of balance Which one of these is NOT part of the middle ear?1 incus malleus cochlea stapes Eustachian tube Which of these is NOT a part of the organ of Corti?1 tympanic membrane hair cells tectorial membrane nerve cells What hertz range is the human voice?1 About 10 to 30 Hz About 100 to 300 Hz About 1,000 to 3,000 Hz 60: Mouth, nose and throat 79: The Skeletal Muscles Back to: 61: The ear
