Or What is the right sequence of bones in the ear ossicles of a mammal starting from the tympanum inwards
OR
The sequence of ossicles starting from outside to inside

Options

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

Answer

To determine the correct sequence of ear ossicles starting from the tympanum (eardrum) inwards, we need to identify the three bones involved in the auditory system of mammals. These bones are known as the malleus, incus, and stapes.

### Step-by-Step Solution:

1. **Identify the Ear Ossicles**:
- The three ear ossicles are:
- Malleus (also known as the hammer)
- Incus (also known as the anvil)
- Stapes (also known as the stirrup)

2. **Understand Their Arrangement**:
- The malleus is the first ossicle that is connected to the tympanic membrane (eardrum).
- The incus is the second ossicle, which is connected to the malleus.
- The stapes is the innermost ossicle, which is connected to the incus.

3. **Sequence from Outside to Inside**:
- Starting from the eardrum (tympanum), the sequence of the ossicles is:
- Malleus (first)
- Incus (second)
- Stapes (third)

4. **Conclusion**:
- Therefore, the correct sequence of the ear ossicles starting from the tympanum inwards is **Malleus → Incus → Stapes**.

5. **Select the Correct Option**:
- Based on the options provided, the correct answer is **Option 1: Malleus, Incus, Stapes**.
