====Intrinsic muscles==== {{Infobox muscle | Name = Intrinsic muscles of external ear | Latin = | Image = Gray906.png | Caption = The muscles of the [[pinna (anatomy)|auricula]] | Image2 = | Caption2 = | Origin = | Insertion = | Blood = | Nerve = [[Facial nerve]] | Action = Undeveloped in humans | Antagonist = }} The '''intrinsic auricular muscles''' are: * The [[helicis major]] is a narrow vertical band situated upon the anterior margin of the [[helix (ear)|helix]]. It arises below, from the [[spina helicis]], and is inserted into the anterior border of the helix, just where it is about to curve backward. * The [[helicis minor]] is an oblique [[Muscle fascicle|fasciculus]], covering the [[crus helicis]]. * The [[tragicus]] is a short, flattened vertical band on the lateral surface of the [[tragus (ear)|tragus]]. Also known as the mini lobe. * The [[antitragicus]] arises from the outer part of the antitragus, and is inserted into the [[cauda helicis]] and [[antihelix]]. * The [[Transverse muscle of auricle|transverse muscle]] is placed on the cranial surface of the [[pinna (anatomy)|pinna]]. It consists of scattered fibers, partly tendinous and partly muscular, extending from the [[eminentia conchae]] to the prominence corresponding with the [[scapha]]. * The [[Oblique muscle of auricle|oblique muscle]] also on the cranial surface, consists of a few fibers extending from the upper and back part of the [[Pinna (anatomy)|concha]] to the convexity immediately above it. The intrinsic muscles contribute to the topography of the auricle, while also function as a sphincter of the external auditory meatus. It has been suggested that during prenatal development in the womb, these muscles exert forces on the cartilage which in turn affects the shaping of the ear.<ref>{{Cite journal |last1=Liugan |first1=Mikee |last2=Zhang |first2=Ming |last3=Cakmak |first3=Yusuf Ozgur |date=2018 |title=Neuroprosthetics for Auricular Muscles: Neural Networks and Clinical Aspects |journal=Frontiers in Neurology |volume=8 |page=752 |doi=10.3389/fneur.2017.00752 |pmid=29387041 |pmc=5775970 |issn=1664-2295 |doi-access=free }}</ref>
