Find the correct order of arrangement of ear ossicles from the side of tympanum towards the oval window.

Options

A. Incus `rarr` stapes `rarr` Malleus
B. stapes `rarr` Incus `rarr` Malleus
C. Malleus `rarr` Incus `rarr` stapes
D. Malleus `rarr` Stapes `rarr` Incus

Answer

To determine the correct order of the ear ossicles from the tympanum (eardrum) towards the oval window, we need to understand the anatomy of the middle ear. The middle ear contains three small bones known as the ossicles, which are crucial for the process of hearing. These ossicles are:

1. **Malleus (Hammer)**: This is the first ossicle that is attached to the tympanic membrane (eardrum).
2. **Incus (Anvil)**: This is the second ossicle that is connected to the malleus on one side and the stapes on the other.
3. **Stapes (Stirrup)**: This is the third ossicle that is connected to the incus and is in contact with the oval window of the cochlea.

### Step-by-Step Solution:

1. **Identify the starting point**: The sequence starts at the tympanum (eardrum).
2. **First ossicle**: The first ossicle in the chain is the **Malleus**, which is directly attached to the tympanic membrane.
3. **Second ossicle**: The next ossicle in the sequence is the **Incus**, which is connected to the malleus.
4. **Third ossicle**: Finally, the last ossicle in the chain is the **Stapes**, which connects to the incus and is attached to the oval window.

### Final Order:
Thus, the correct order of the ear ossicles from the tympanum towards the oval window is:
**Malleus → Incus → Stapes**.
