Anatomy of the Ear

What is the function of the cochlea?

• Funnels sound from the outer ear to the eardrum

• Transmits signals from the cochlea to the brain

• Snail-shaped hearing organ

• Tubes in the inner ear that control balance

What is the role of the eardrum?

• Funnels sound from the outer ear to the eardrum

• Sticks out from the head; Latin for "wing"

• Tympanic membrane: separates the outer ear from the inner ear

• Transmits signals from the cochlea to the brain

What does the Eustachian tube do?

• Connects the back of the nose to the middle ear; supplies middle ear with air

• Funnels sound from the outer ear to the eardrum

• Tubes in the inner ear that control balance

• Anvil: a bone that helps transmit sound waves from the outer ear to the cochlea

What is the function of the external auditory canal?

• Funnels sound from the outer ear to the eardrum

• Sticks out from the head; Latin for "wing"

• Hammer: a bone that helps transmit sound waves from the outer ear to the cochlea

What is the incus?

• Snail-shaped hearing organ

• Anvil: a bone that helps transmit sound waves from the outer ear to the cochlea
