The structure that transmits vibration to the inner ear is a modified 

Options

A. stapes
B. malleus
C. sacculus
D. hyomandibular

Answer

To solve the question "The structure that transmits vibration to the inner ear is a modified...", we need to identify which of the given options is the correct structure responsible for transmitting vibrations to the inner ear.

### Step-by-Step Solution:

1. **Understand the Question**: We need to find out which structure transmits vibrations to the inner ear. The question suggests that this structure is a modified version of something else.

2. **Analyze the Options**: The options provided are:
- A) Stapes
- B) Malleus
- C) Incus
- D) Hyomandibular

3. **Identify Each Option**:
- **Stapes**: This is a small stirrup-shaped bone located in the middle ear. It is known to transmit vibrations from the middle ear to the inner ear.
- **Malleus**: Also known as the hammer, this bone is one of the three ossicles in the middle ear. It connects the eardrum to the incus.
- **Incus**: This is the anvil-shaped bone that is also part of the ossicles, situated between the malleus and the stapes.
- **Hyomandibular**: This is a set of bones found in the hyoid region of many fishes, primarily involved in jaw suspension.

4. **Determine the Correct Answer**: The stapes is the structure that transmits vibrations to the inner ear. It is a modified bone that plays a crucial role in hearing by transferring sound vibrations from the middle ear to the inner ear.

5. **Final Answer**: The structure that transmits vibration to the inner ear is a modified **Stapes**.
