72. Pinna (auricle) - 1 - Collects and funnels sound waves into the ear canal.
73. incus (anvil) ear bone - 5 - Transmits vibrations from the malleus to the stapes.
74. malleus (hammer) ear bone - 2 - Transmits vibrations from the eardrum to the incus.
75. tympanic membrane (eardrum) - 4 - Vibrates in response to sound waves, transmitting them to the ossicles.
76. stapes (stirrup) ear bone - 6 - Transmits vibrations from the incus to the oval window of the cochlea.
77. semicircular canals - 7 - Detect rotational acceleration and deceleration of the head for balance.
78. cochlea - 9 - Converts mechanical sound vibrations into electrical signals for the brain.
79. vestibulocochlear nerve - 10 - Carries auditory and balance information from the inner ear to the brain.
80. middle ear - 3 - Contains the ossicles and amplifies sound vibrations before they enter the inner ear.
81. eustachian tube - 11 - Equalizes air pressure on both sides of the eardrum.
82. auditory canal - 12 - Channels sound waves from the pinna to the eardrum.
Parent Tip: Review the logic above to help your child master the concept of parts of the ear worksheet.
