作为一个肌肉静水器，舌头在大多数口腔行为中都会发生复杂的变形，包括咀嚼和喝水。在这些行为中，变形与舌头和下巴的运动一起发生，以定位和运输药丸。此外，舌头的各个部分可能在相对于开口周期的相似时间点移动和变形，也可能发生在不同的时间点，这表明了区域生物力学和功能的差异。本研究的目的是通过描述舌头尺寸（即长度和宽度）在多个区域同时发生的内在变化，量化猪咀嚼和饮水过程中的舌头变形。与喝水周期相比，咀嚼周期的舌头变形通常更大。咀嚼和喝水的时间也不同，相对于区域长度和宽度的间隙周期，但不是总长度，变形。这表明在局部形状变化的时间动态中存在功能差异，而下颌-舌头协调的全局特性则保持不变。最后，长度和宽度变形之间的权衡差异表明，肌肉静水器的特性在整个舌头水平上都可以观察到，但在区域水平上存在生物力学变化（例如，运动和变形的变化）。这项研究为舌形变形的区域贡献提供了新的关键见解，为未来软组织多维形状变化的工作奠定了基础。
As a muscular hydrostat, the tongue undergoes complex deformations during most oral behaviors, including chewing and drinking. During thesebehaviors, deformations occur in concert with tongue and jaw movements to position and transport the bolus. Moreover, the various parts of the tongue may move and deform at similar timepoints relative to the gape cycle or they may occur at different timepoints, indicating regional biomechanical and functional variation. The goal of this study is to quantify tongue deformations during chewing and drinking in pigs by characterizing intrinsic changes in tongue dimensions (i.e., length and width) across multiple regions simultaneously. Tongue deformations are generally larger during chewing cycles compared to drinking cycles. Chewing and drinking also differ in the timing, relative to the gape cycle, of regional length and width, but not total length, deformations. This demonstrates functional differences in the temporal dynamics of localized shape changes, whereas the global properties of jaw–tongue coordination are maintained. Finally, differences in the trade-off between length and width deformations demonstrate that the properties of a muscular hydrostat are observed at the whole tongue level, but biomechanical variation (e.g., changes in movements and deformations) at the regional level exists. This study provides new critical insights into the regional contributions to tongue deformations as a basis for future work on multidimensional shape changes in soft tissues.
