Question

Arrange in sequence the following events related to the mechanism of hearing:

• Hair cells bend and press against Tectorial membrane.
• The induction of ripple in basilar membrane.
• Eardrum vibrates in response to sound waves.
• Impulses transmitted to brain.
• Transmission of vibrations through ear ossicles.

• A. C, E, B, A, D
• B. B, A, D, E, C
• C. D, C, B, E, A
• D. C, B, E, D, A

Hint:

The correct sequence for the mechanism of hearing involves the eardrum vibrating first, followed by transmission through the ossicles, ripple induction in the basilar membrane, bending of hair cells, and transmission of impulses to the brain.

Answer 1

The Correct Option is A

The sequence of events involved in the mechanism of hearing is:
1. The eardrum vibrates in response to sound waves. (C)
2. The transmission of vibrations through the ear ossicles. (E)
3. The induction of a ripple in the basilar membrane. (B)
4. Hair cells bend and press against the Tectorial membrane. (A)
5. Impulses are transmitted to the brain. (D)
Hence, the correct sequence is C, E, B, A, D.
