Ear Anatomy and Sound Assessment

What is the primary function of the auditory canal?

• Transmit sound vibrations to the cochlea

• Amplify sound waves

• Direct sound waves toward the tympanic membrane

• Convert sound waves into electrical signals

The tympanic membrane is also known as the:

• Cochlea

• Eustachian tube

• Eardrum

• Oval window

What is the function of the ossicles?

• Detect sound vibrations

• Amplify sound waves and transmit them to the cochlea

• Convert sound waves into nerve impulses

• Equalize pressure between the middle ear and throat

The malleus, incus, and stapes are parts of the:

• Auditory canal

• Cochlea

• Vestibule

• Ossicles

The cochlea is responsible for:

• Balancing the body

• Detecting sound vibrations and converting them into electrical signals

• Equalizing pressure in the ear

• Amplifying sound waves

Sensory hair cells are located in the:

• Auditory canal

• Cochlear nerve

• Cochlea

• Eustachian tube

What role do sensory hair cells play in hearing?

• Balance body movement

• Convert sound vibrations into electrical signals

• Amplify sound

• Maintain ear pressure

The cochlear nerve carries signals from the:

• Eustachian tube to the brain

• Auditory canal to the middle ear

• Cochlea to the brain

• Vestibule to the brain

The oval window receives vibrations from the:

• Auditory canal

• Tympanic membrane

• Ossicles

• Cochlear nerve

What is the vestibule's primary function?

• Convert sound waves into electrical signals

• Maintain balance and spatial orientation

• Amplify sound waves

• Transmit signals to the cochlear nerve
