Question

The sequence of ear ossicles from outside (tympanum) to inside is

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

Answer 1

Answer: (B)

Malleus, incus and stapes

The middle ear consists of three bones or ossicles:

• Malleus (hammer)
• Incus (anvil)
• Stapes (stir-up)

These bones are attached to each other in a chain-like manner. Malleus is attached to tympanic membrane whereas stapes is attached to oval window of cochlea.

Hence, the sequence of ear ossicles from outside to inside is: malleus, incus and stapes.

So, the correct answer is 'Malleus, incus and stapes'.
