The purpose of this investigation was to identify the composition and organization of lingual tissues underlying the histostructural and biomechanical functions of the adult human tongue. The small-scale structures of three intrinsic muscle regions, their principal cells, structural complexities, and differences in underlying tissue composition were compared to other skeletal muscle systems and the results discussed in relation to lingual morphology. Analysis of pixel color distributions determined the percent area concentration of each stained tissue component. Results indicated that muscle content increased from anterior to posterior (p <.0001). Greater adipose (p =.005) and connective tissue (p <.002) concentrations occurred in anterior regions. Dense collagen sheaths and elastic fibers found anteriorly occurred with less magnitude in medial and posterior sites. The unique elastin, collagen, and adipose connective tissue distributions found in intrinsic sampling sites are discussed in terms of understanding lingual biomechanics in both normal and pathologic states.
本研究的目的是确定成年人类舌头组织结构和生物力学功能背后的舌组织的组成和结构。将三个舌内肌区域的微观结构、其主要细胞、结构复杂性以及潜在组织组成的差异与其他骨骼肌系统进行比较，并结合舌形态学讨论结果。通过分析像素颜色分布确定每个染色组织成分的面积百分比浓度。结果表明，肌肉含量从舌前部到后部增加（p <.0001）。前部区域的脂肪（p =.005）和结缔组织（p <.002）浓度更高。在前部发现的致密胶原鞘和弹性纤维在内侧和后部部位的数量较少。从理解正常和病理状态下的舌生物力学角度，讨论了在舌内采样部位发现的独特的弹性蛋白、胶原蛋白和脂肪结缔组织分布情况。
