Ear

Question 1

What is the function of the auditory nerve?

Answer 1

Sends nerve impulses from the cochlea to the brain

The auditory nerve is crucial for hearing as it transmits sound information to the brain for interpretation.

Question 2

What does the inner ear contain?

Answer 2

Fluid

The fluid in the inner ear is essential for balance and hearing.

Question 3

What is the role of the semicircular canals?

Answer 3

Detect the position of the head and help to balance the body

Semicircular canals are part of the vestibular system, which is responsible for maintaining balance.

Question 4

What does the cochlea do?

Answer 4

Detects and converts sound vibrations into nerve impulses

The cochlea is a spiral-shaped organ that plays a critical role in the auditory system.

Question 5

What is the function of the Eustachian tube?

Answer 5

Balances the air pressure on both sides of the eardrum

The Eustachian tube connects the middle ear to the back of the throat and helps equalize pressure.

Question 6

What is the oval window’s function?

Answer 6

Transfers sound vibrations to the cochlea

The oval window is a membrane-covered opening that leads from the middle ear to the cochlea.

Question 7

What are the ossicles made up of?

Answer 7

Three small bones

The ossicles include the malleus, incus, and stapes, which amplify sound vibrations.

Question 8

What is the role of the eardrum?

Answer 8

Vibrates according to the frequency of the sound waves

The eardrum is a thin membrane that plays a vital role in the hearing process.

Question 9

What does the ear canal do?

Answer 9

Directs sound waves to the eardrum

The ear canal is the passage that leads sound waves from the outer ear to the eardrum.

Question 10

What does the outer ear include?

Answer 10

Earlobe

The outer ear collects and directs sound waves into the ear canal.

Question 11

Fill in the blank: The _______ collects and transfers sound vibrations from the ossicles.

Answer 11

Oval window

The oval window plays a crucial role in transmitting sound vibrations from the middle ear to the inner ear.

Question 12

True or False: The middle ear contains fluid.

Answer 12

False

The middle ear contains air and houses the ossicles, while the inner ear contains fluid.

Question 13

What are the functions of the parts of the human ear?

Answer 13

Detect sound, balance, amplify sound, transfer vibrations

Each part of the ear has specific functions contributing to hearing and balance.
