Hearing sensation

Q. Sort the order by which the sound waves travel through the ear for interpretation.

1. Brain
2. Cochlea
3. Ear ossicles
4. Ear drum
5. Pinna

Q.

The site of nerve impulse for hearing originates from

1. Cochlea

2. Auditory nerve

3. Ear drum

4. Ear ossicles

Q. Assertion (A): People feel dizzy for a while after getting down from the roller coaster ride.

Reason (R): Damage to the vestibular system affects the sense of balance and spatial orientation.

1. Both A and R are true and R is the correct explanation of A
2. Both A and R are true but R is not the correct explanation of A
3. A is true but R is false
4. A is false but R is true

Q. Which of the following is true about the ear?

1. Eustachian tube equalizes the air pressure outside the ear.
2. Auditory impulses are transmitted to the brain via auditory nerves.
3. Eardrum collects the sound waves and sends them to the inner ear.
4. Vestibular apparatus ensures that we maintain our body balance.

Q.

Name the organ where cochlea is located and give its functions.

Q.

Mention one role of the ear ossicles.

Q.

explain the function of cochela and audiatry nerve by following example of human ear structure

Q. Assertion (A): People feel dizzy for a while after getting down from the roller coaster ride.

Reason (R): Damage to the vestibular system affects the sense of balance and spatial orientation.

1. A is true but R is false
2. A is false but R is true
3. Both A and R are true but R is not the correct explanation of A
4. Both A and R are true and R is the correct explanation of A

Q. Identify the sequence in which the sound vibrations reach the brain:
$\begin{array}{cc}\text{Parts}& \text{Function}\\ \left(a\right)\text{External ear}& \left(i\right)\text{Amplifies the vibrations received on the tympanic membrane.}\\ \left(b\right)\text{Middle Ear}& \left(ii\right)\text{Converts the vibrations into nerve impulses and sends them to brain.}\\ \left(c\right)\text{Inner Ear}& \left(iii\right)\text{Directs the sound waves towards the tympanic membrane.}\end{array}$

1. a-i, b-iii, c-ii
2. a-iii, b-i, c-ii
3. a-ii, b-iii, c-i
4. a-ii, b-i, c-iii

Q.

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

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

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

3. It helps in maintaining the balance of pressure.

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