Understanding the Ear: Structure and Function

What is the primary function of the pinna in the outer ear?

• To amplify sound

• To capture and funnel sound waves

• To balance pressure

• To detect rotational motion

Which structure marks the beginning of the middle ear?

• Eustachian tube

• Tympanic membrane

• Cochlea

• Pinna

What happens when the tympanic membrane vibrates?

• It detects rotational motion

• It equalizes pressure

• It causes the ossicles to vibrate

• It sends signals directly to the brain

What is the role of the ossicles in the ear?

• To sense linear acceleration

• To equalize pressure

• To amplify sound vibrations

• To detect sound waves

Which part of the ear is responsible for sensing linear acceleration?

• Cochlea

• Pinna

• Semicircular canals

• Vestibule

What do the semicircular canals detect?

• Rotational motion

• Linear acceleration

• Sound waves

• Pressure changes

Where are the auditory receptors located?

• In the Eustachian tube

• In the tympanic membrane

• In the cochlea

• In the pinna

How do auditory receptors send information to the brain?

• Through the Eustachian tube

• Via the auditory nerve

• By vibrating the tympanic membrane

• Through the semicircular canals

Which structure is involved in detecting rotational motion?

• Cochlea

• Vestibule

• Pinna

• Semicircular canals

What is the function of the Eustachian tube?

• To detect sound waves

• To amplify sound

• To equalize pressure

• To sense rotational motion
