Among the three ear ossicles. A receives the sound vibration from tympanum while B passes them to fenestra ovalis

Options

A. A stirrup B Malleus
B. A Anvil B Stapes
C. A Malleus B Anvil
D. A Malleus B stapes

Answer

To solve the question regarding the three ear ossicles and their functions, we can break it down step by step:

### Step-by-Step Solution:

1. **Identify the Ear Ossicles**: The three ear ossicles are:
- Malleus (Hammer)
- Incus (Anvil)
- Stapes (Stirrup)

2. **Function of the Tympanum**: The tympanum, commonly known as the eardrum, receives sound vibrations from the external environment. It acts as a barrier between the outer ear and the middle ear.

3. **Identify the Ossicle Receiving Sound from the Tympanum**:
- The Malleus is the first ossicle that receives vibrations from the tympanum. It is directly attached to the eardrum.

4. **Identify the Ossicle Passing Vibrations to the Fenestra Ovalis**:
- The Stapes is the ossicle that transmits vibrations to the fenestra ovalis (oval window), which is the membrane-covered opening that leads to the inner ear.

5. **Conclusion**:
- Therefore, in the context of the question:
- A (the ossicle receiving sound vibrations from the tympanum) is the Malleus.
- B (the ossicle passing vibrations to the fenestra ovalis) is the Stapes.

6. **Final Answer**: The correct pairing is Malleus (A) and Stapes (B).
