The auricle or auricula is the visible part of the ear that resides outside of the head. It is also called the pinna (Latin for ''wing'' / ''fin'', plural pinnae), a term that is used more in zootomy. ==Structure== The diagram shows the shape and location of most of these components: *''Anthelix'' (''antihelix'') forms a 'Y' shape where the upper parts are: * *''Superior crus'' (to the left of the ''fossa triangularis'' in the diagram) * *''Inferior crus'' (to the right of the ''fossa triangularis'' in the diagram) *''Antitragus'' is below the ''tragus'' *''Aperture'' is the entrance to the ear canal *''Auricular sulcus'' is the depression behind the ear next to the head *''Concha'' is the hollow next to the ear canal *Conchal angle is the angle that the back of the ''concha'' makes with the side of the head *''Crus'' of the helix is just above the ''tragus'' *''Cymba conchae'' is the narrowest end of the ''concha'' *External auditory meatus is the ear canal *''Fossa triangularis'' is the depression in the fork of the ''antihelix'' *Helix is the folded over outside edge of the ear *''Incisura anterior auris'', or intertragic incisure, or intertragal notch, is the space between the ''tragus'' and ''antitragus'' *Lobe (lobule) - attached or free according to a classic single-gene dominance relationship *''Scapha'', the depression or groove between the helix and the anthelix *Tragus 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Auricle (anatomy)」の詳細全文を読む スポンサード リンク
