Correct order of ear ossicles in rabbit is :

Options

A. Incus, stapes, malleus
B. Malleus, incus, stapes
C. Malleus, stapes, incus
D. Incus, malleus, stapes

Answer

To determine the correct order of ear ossicles in a rabbit, we need to identify the three auditory ossicles and their arrangement. The ear ossicles consist of three small bones located in the middle ear, which are essential for hearing as they amplify sound waves.

### Step-by-Step Solution:

1. **Identify the Ear Ossicles**: The three ear ossicles in mammals, including rabbits, are the Malleus, Incus, and Stapes.
- Malleus (hammer-shaped)
- Incus (anvil-shaped)
- Stapes (stirrup-shaped)

2. **Understand Their Arrangement**: The arrangement of these ossicles is crucial for sound transmission. The Malleus is the first bone that is connected to the tympanic membrane (eardrum). The Incus is the second bone that connects to the Malleus, and the Stapes is the third bone that connects to the Incus.

3. **Correct Order**: Based on their anatomical arrangement, the correct order of the ear ossicles in a rabbit is:
- Malleus → Incus → Stapes

4. **Evaluate the Options**:
- Option 1: Stapes, Malleus (Incorrect)
- Option 2: Malleus, Incus, Stapes (Correct)
- Option 3: Malleus, Trapezius, Incus (Incorrect)
- Option 4: Incus, Malleus, Stapes (Incorrect)

5. **Conclusion**: The correct answer is Option 2: Malleus, Incus, Stapes.
