The morphology of the more superficial tissue of the human tongue was investigated and discussed with the clinical appearance of fissures. Three regions could be distinguished according to the presence and shape of the aponeurosis linguae: the central region showed a thick aponeurotic plate with myotendinous muscle fibre insertions. The lateral region showed still an aponeurosis linguae but of reduced thickness and without muscle insertions. The edge-wise and lower region showed no aponeurosis linguae but a fatty subcutis and myocutaneous muscle fibre insertions lacking specific molecules of myotendinous junctions. This system of partially developed exoskeleton seems to underlie but not to be involved in tongue fissures, which are more superficial within the epidermis and dermis.
研究了人类舌头更浅层组织的形态，并结合裂缝的临床外观进行了讨论。根据舌腱膜的存在和形状，可以将其分为三个区域：中央区域显示出厚的腱膜板，有肌肉肌腱纤维插入。侧区仍然有舌腱膜，但厚度减小，没有肌肉插入。边缘和下部区域没有舌腱膜，但有脂肪皮下组织和肌纤维插入，缺乏肌腱结合处的特定分子。这种部分发育的外骨骼系统似乎是舌头裂缝的基础，但不参与其中，裂缝更表浅，位于表皮和真皮内。
