翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Torus tubarius ： ウィキペディア英語版 Torus tubarius The base of the cartilaginous portion of the eustachian tube (pharyngotympanic tube; auditory tube) lies directly under the mucous membrane of the nasal part of the pharynx, where it forms an elevation, the torus tubarius, the torus of the auditory tube, or cushion, behind the pharyngeal orifice of the tube. The torus tubarius is very close to the tubal tonsil,〔http://download.videohelp.com/vitualis/med/pharynx.htm〕 which is sometimes also called the ''tonsil of (the) torus tubarius''.〔http://www.almaany.com/home.php?language=english&lang_name=English&category=Medical&word=tonsil+of+torus+tubarius++%3D++tubal+tonsil〕 Equating the torus with its tonsil however might be seen as incorrect or imprecise. Two folds run posteriorly and anteriorly: *posteriorly, the vertical fold of mucous membrane, the salpingopharyngeal fold, stretches from the lower part of the torus tubarius; it contains the Salpingopharyngeus muscle which origin from the superior border of medial lamina of the cartilage,〔(FUNCTIONAL ANATOMY OF THE EUSTACHIAN TUBE. CLEVELAND S. SIMKINS, PH.D. Arch Otolaryngol. 1943;38(5):476-484. )〕 it passes downward and blends with the posterior fasciculus of the palatopharyngeus muscle. *anteriorly, the second and smaller fold, the salpingopalatine fold, smaller than the salpingopharyngeal fold, contains some fibers of muscle, called ''salpingopalatine muscle'' by Simkins (1943),〔 it stretches from the superior border of lateral lamina of the cartilage, anteroinferiorly, to the back of the hard palate. The tensor veli palatini does not contribute to the fold, since the origin is deep to the cartilaginous opening. ==References== 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「Torus tubarius」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
