Which of the following is the function of ear ossicles ?

Options

A. To collect the vibrations in the air
B. To equalise the pressures on either sides of the ear drum
C. To secrete ear wax
D. To increase the efficiency of transmission of sound waves to the inner ear

Answer

**Step-by-Step Solution:**

1. **Understanding Ear Ossicles**: Ear ossicles, also known as auditory ossicles, are three tiny bones located in the middle ear. They are the smallest bones in the human body and play a crucial role in hearing.

2. **Identifying the Function**: The primary function of the ear ossicles is to transmit sound vibrations from the eardrum to the cochlea, which is part of the inner ear.

3. **Process of Sound Transmission**: When sound waves enter the ear, they cause the eardrum to vibrate. These vibrations are then passed to the ossicles. The three ossicles (malleus, incus, and stapes) amplify these vibrations before they reach the cochlea.

4. **Evaluating the Options**:
- **Option A**: "To collect the vibration in the ear" - This is incorrect as the ear collects sound waves, but the ossicles do not collect vibrations.
- **Option B**: "To equalize the pressure on either sides of the eardrum" - This is also incorrect; this function is performed by the Eustachian tube.
- **Option C**: "To secrete the earwax" - This is incorrect; earwax is secreted by glands in the ear canal, not by the ossicles.
- **Option D**: "To increase the efficiency of transmissions of sound waves to the inner ear" - This is the correct function of the ear ossicles.

5. **Conclusion**: Based on the analysis, the correct answer is that the function of ear ossicles is to increase the efficiency of transmission of sound waves to the inner ear.

**Final Answer**: To increase the efficiency of transmissions of sound waves to the inner ear.
