Ossicles Auditory

**Auricular bones** - (Auricular ossicula, pna., bna.; Ossicula Tympanum, JNA) are bones that are part of the middle ear system and ensure the transmission of sound waves into the cavity of the inner ear. They are located in the temporal bone of the skull and are connected to each other by a thin cord. The average human ear has only 3 bones. Two of them - the malleus and the incus - are involved in transmitting the sound signal to the tympanic cavity. The middle bone is called the stirrup. Thus, the 3 parts of the human middle ear perform key functions in the formation of auditory sensations.

In different anatomical reference books this area may have different meanings. But basically this term refers to a separate bone, which has no practical use. The bone is located in the auricle, which houses earwax. Because over the course of a lifetime it builds up on top of each other in several layers and partially even comes out through holes located along the edge of the ear. If the integrity of this structure is violated, we can say that the bone is missing. The condition when the external component is completely absent is rare. Most often, bone fragments and individual areas can be found. There are cases where part of this structure is lost. The main function of this area is to ensure the flow of air during breathing.
