Exploring the Human Ear

What are the three main parts of the ear?

• Outer ear, vestibule, semicircular canals

• Outer ear, auditory canal, tympanic membrane

• Outer ear, middle ear, inner ear

• Outer ear, eardrum, cochlea

Describe the function of the cochlea in hearing.

• The cochlea is responsible for producing sound waves in the ear.

• The cochlea functions to convert sound vibrations into electrical signals for the brain to process.

• The cochlea filters out background noise to enhance hearing.

• The cochlea amplifies sound waves before they reach the brain.

How does sound travel from the outer ear to the inner ear?

• Sound moves through the bloodstream to the brain.

• Sound travels through the nasal passages and throat.

• Sound travels from the outer ear to the inner ear through the ear canal, eardrum, ossicles, and cochlea.

• Sound is transmitted via the optic nerve.

What role do the ossicles play in the hearing process?

• The ossicles amplify sound vibrations and transmit them to the inner ear.

• The ossicles are responsible for balance and spatial orientation.

• The ossicles produce sound waves in the ear.

• The ossicles filter out background noise.

Explain how the brain interprets sound signals received from the ear.

• Sound signals are interpreted by the visual cortex instead of the auditory cortex.

• The brain interprets sound signals by converting vibrations from the ear into electrical signals, which are then processed in the auditory cortex.

• The brain uses chemical signals to interpret sound vibrations.

• The brain amplifies sound waves before sending them to the ear.
