Question

Write short note on ear ossicles.

Answer 1

The middle ear contains a flexible chain of three middle bones called as ear ossicles. The three ear ossicles are malleus, incus and 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 to an oval membrane, fenestra ovalis, of the internal ear. The ear ossicles act as a lever that transmits sound waves from external ear to internal ear.
