External and Middle Ear

Q. The three bones in the middle ear are collectively called:

1. Pinna
2. Ear ossicles
3. Tympanum
4. Semicircular canals

Q.

Which of the following is the correct function of tympanic membrane?

1. It helps in maintaining the balance of the body.

2. It helps in maintaining the balance of pressure.

3. It helps in the vibration of air inside the cochlea.

4. It transmits vibrations through the ear ossicles to the oval window.

Q.

__________ collects sound waves and carries them to the auditory canal.

1. Tympanum

2. Pinna

3. Malleus

4. Ear wax

Q.

Amplification and transmission of the vibrations received by tympanum into the inner ear are done by:

1. Cochlea

2. Eustachian tube

3. Ear ossicles

4. Perilymph

Q.

In human beings, the middle ear ossicles, from inside to outside, are in the sequence of:

1. Stapes, malleus, incus

2. Incus, malleus, stapes

3. Malleus, incus, stapes

4. Stapes, incus, malleus

Q.

Which of these is the main function of the pinna?

1. It converts sound waves into mechanical vibrations

2. It converts sound vibrations into sound waves

3. It converts sound vibrations into electrical impulses

4. It collects sound waves and channels them into the ear.

Q. Choose the correct sequence based on transmission of the sound waves from the outer ear to the brain.

1. Pinna → tympanic membrane → auditory canal → cochlea → malleus → incus → stapes → auditory nerve
2. Pinna → malleus → incus → stapes → auditory canal → tympanic membrane → cochlea → auditory nerve
3. Pinna → auditory canal → tympanic membrane → malleus → incus → stapes → cochlea → auditory nerve
4. Pinna → cochlea → tympanic membrane → auditory membrane → auditory canal → incus → malleus → stapes → cochlea → auditory nerve

Q. Which of these constitute the outer ear?

1. Earlobe
2. Cochlea
3. Auditory canal
4. Eustachian canal
