Question
Write short note on ear ossicles.
✓

Answer

The middle ear contains a flexible chain of three middle bones called ear ossicles. The three ear ossicles are as follows.
  1. Malleus
  2. Incus
  3. Stapes
The malleus is attached to tympanic membrane on one side and to incus on the other side. The incus is connected with stapes. Stapes, in turn, are attached with an oval membrane, fenestra ovalis, of internal ear. The ear ossicles act as a lever that transmits sound waves from external ear to internal ear.
