or &#039;&#039;&#039;external acoustic meatus&#039;&#039;&#039;, is a tube running from the outer ear to the middle ear. The human auditory meatus extends from the [[pinna (anatomy)|pinna]] to the [[tympanic membrane|eardrum]] and is approximately 2.5 centimeters in length and 0.7 centimeters in diameter.<br /> <br /> == Anatomy ==<br /> <br /> The auditory meatus is divided into two parts: the outer third, which is cartilaginous, and the inner two-thirds, which is bony. The cartilaginous portion is surrounded by the [[cartilage]] of the pinna and contains numerous [[sebaceous glands]] and [[ceruminous glands]], which produce [[earwax]]. The bony portion is narrower and is lined with thin, sensitive skin.<br /> <br /> == Function ==<br /> <br /> The primary function of the auditory meatus is to transmit sound from the pinna to the eardrum. The shape and length of the canal, particularly the bony portion, help to amplify sounds in the frequency range of human speech. The auditory meatus also protects the eardrum by maintaining a constant humidity and temperature, and by producing earwax, which helps to trap dust and other particles.<br /> <br /> == Clinical significance ==<br /> <br /> Conditions that can affect the auditory meatus include [[otitis externa]], commonly known as swimmer&#039;s ear, which is an inflammation of the external ear and auditory meatus. Other conditions include [[cerumen impaction]], or excessive earwax, and [[exostosis]], which is the formation of new bone on the surface of the bone, often caused by prolonged exposure to cold water.<br /> <br /> == See also ==<br /> * [[Ear]]<br /> * [[Middle ear]]<br /> * [[Inner ear]]<br /> * [[Eardrum]]<br /> * [[Otitis externa]]<br /> * [[Cerumen impaction]]<br /> * [[Exostosis]]<br /> <br /> [[Category:Ear]]<br /> [[Category:Auditory system]]<br /> {{anatomy-stub}}</div> Prab
