Question

How many pairs of ear ossicles are there?

Answer 1

Hint: The bones of the ear, also known as the auditory ossicles, are the three smallest bones in the human body. These bones play an important role in the sense of hearing by transmitting sounds to the inner ear. The three audible ossicles — the malleus, incus, and stapes — are small bones found in the middle ear. Each bone is named in Latin for its shape: Malleus implies mallet or hammer ,Incus implies anvil and Stapes implies stirrup.

Complete answer:
Ear bone, likewise called Auditory Ossicle, any of the three small bones in the center ear, all things considered. These are the malleus, or mallet, the incus, or iron block, and the stapes, or stirrup. Together they structure a short chain that crosses the center ear and sends vibrations brought about by sound waves from the eardrum layer to the fluid of the internal ear. The malleus takes after a club more than a hammer, while the incus resembles a premolar tooth with a broad root framework. The stapes does intently look like a stirrup. The top or top of the malleus and the body of the incus are held together by a firmly fitting joint and are situated in the attic, or upper part, of the eardrum cavity. The handle of the malleus sticks to the upper portion of the drum membrane. Three little ligaments hold the top of the malleus, and a fourth connects a projection (called the short process) from the incus to a slight depression in the back mass of the cavity. The long process of the incus is bowed close to the lower end and conveys a little knoblike bone that is jointed freely to the top of the stapes—the third and littlest of the ossicles. The stapes lies in a level situation at right points with the long process of the incus.

Note: The middle ear is the segment of the ear inside to the eardrum, and outside to the oval window of the inward ear. The mammalian middle ear contains three ossicles, which move the vibrations of the eardrum into waves in the liquid and membrane of the inward ear.There are three ossicles in every ear : Malleus, Incus, Stapes. As we have a couple of ears, so altogether there are 6 ossicles, or 3 sets of ossicles.
