Answer:
The three bones present in the ear are malleus, incus and stapes
Explanation:
→ The three bones are present in the middle ear and are also called as ossicles.
→ The bones are attatched to each other in a chain like fashion.
→ The bones are hammer shaped and increase the efficiency of sound transmission to the inner ear.
→ Malleus is attatched to the tympanic membrane and stapes is attatched to the oval window of cochlea.
→ The two openings of the tympanic cavity are called Fenestra ovalis (oval window) and Fenestra rotunda (round window).
→ The cochlea is the main hearing organ of the inner ear. It has two canals, an upper Scala vestibuli and a lower Scala tympanum which is separated by a scala media.
→ The canals are filled with a fluid called as the endolymph.
