In human anatomy, juncturae tendinum refers to the connective tissues that link the tendons of the extensor digitorum communis, and sometimes, to the tendon of the extensor digiti minimi. Juncturae tendinum are located on the dorsal aspect of the hand in the first, second and third inter-metacarpal spaces proximal to the metacarpophalangeal joint. == Structure == Juncturae tendinum are narrow bands of connective tissues that extend between the tendons of the extensor digitorum communis and the extensor digiti minimi.〔 It is classified into three distinct types (Type 1, 2 and 3) depending on morphology. * Type 1: This is a thin and filamentous juncturae tendinum. Its shape can either be square, rhomboidal or triangular.〔 * Type 2: This type is more tendinous and thicker than type 1 juncturae, and it is also located more distal than the type 1.〔 * Type 3: Type 3 juncturae refers to the slips from the extensor digitorum communis.〔 Type 3 juncture is further divided into subtype 3r and 3y according to its shape,〔 with the subtype 3r being more oblique than the 3y.〔 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「Juncturae tendinum」の詳細全文を読む スポンサード リンク
