It is a significant component of the [[temporal bone]], which is one of the bones that make up the [[skull]] in vertebrates.<br /> <br /> == Anatomy ==<br /> <br /> The tympanic part of the temporal bone is located in the [[skull]] and forms the anterior and inferior walls and a part of the posterior wall of the external acoustic meatus, which is the tube through which sound travels to reach the [[eardrum]]. It also contributes to the floor and part of the anterior wall of the tympanic cavity, which houses the [[middle ear]].<br /> <br /> == Structure ==<br /> <br /> The tympanic part of the temporal bone is curved and roughly quadrilateral in shape. It has two surfaces and four borders. The lateral surface is concave and forms the anterior wall, the floor, and part of the posterior wall of the external acoustic meatus. The medial surface forms the floor and part of the anterior wall of the tympanic cavity.<br /> <br /> == Development ==<br /> <br /> The tympanic part of the temporal bone is derived from the first [[pharyngeal arch]] during embryonic development. It starts as a ring of bone that gradually expands to form the tympanic part of the temporal bone.<br /> <br /> == Clinical Significance ==<br /> <br /> Damage to the tympanic part of the temporal bone can result in hearing loss or other auditory issues. It can also be affected by various diseases, including [[otitis media]], [[cholesteatoma]], and [[temporal bone cancer]].<br /> <br /> == See Also ==<br /> <br /> * [[Temporal bone]]<br /> * [[Middle ear]]<br /> * [[Eardrum]]<br /> <br /> == References ==<br /> <br /> &lt;references /&gt;<br /> <br /> [[Category:Human anatomy]]<br /> [[Category:Bones of the head and neck]]<br /> [[Category:Temporal bone]]</div>
