Or
The sequence of ossicles starting from outside to inside

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

Answer 1

Answer: (B)

Incus, malleus, stapes

B. Incus, malleus, stapes

Reason: The ossicles (also known as auditory ossicles) are three bones in the middle ear that are among the smallest bones in the human body. They serve to transmit sounds from the tympanic membrane (eardrum) to the fluid-filled labyrinth (cochlea).

The absence of the auditory ossicles would constitute a moderate to severe hearing loss. Starting from outside towards inside, the name of the bones are Incus, Malleus, and Stapes respectively.

So the correct answer is B.
