对哺乳动物咀嚼过程中舌头变形的了解有限，但受益于多平面成像技术的最新发展。在这里，我们展示了标准化的不透射线标记植入物配置和双平面透视如何量化猪咀嚼过程中的三维形状变化。标记之间的三维角度的横向和矢状分量能够表征解剖学相关方向上的变形。横向分量表示向左或向右弯曲，这可以对称或不对称地发生，后者有时表示区域加宽。矢状分量反映了背腹维度对称或不对称的“拱形”或凸形变形，后者是扭曲的特征。在横向和矢状平面及其组合中检测趋势，以修改复杂变形中的舌头形状。还在关键的下巴和舌头位置测量了横向和矢状分量，显示了特别是在最大和最小张口方面的可变性。这凸显了这样一个事实：与舌头位置不同，舌头变形更独立于下颌位置，可能是对不断变化的丸剂形状和位置的响应。从方法论的角度来看，我们的研究展示了适合不同体型动物的可重复三标记植入物配置的优点，并强调了不同植入模式的考虑因素。本文是主题“食品加工和动物营养同化”的一部分。
Understanding of tongue deformations during mammalian mastication is limited, but has benefited from recent developments in multiplanar imaging technology. Here, we demonstrate how a standardized radiopaque marker implant configuration and biplanar fluoroscopy can quantify three-dimensional shape changes during chewing in pigs. Transverse and sagittal components of the three-dimensional angle between markers enable characterizing deformations in anatomically relevant directions. The transverse component illustrates bending to the left or to the right, which can occur symmetrically or asymmetrically, the latter sometimes indicating regional widening. The sagittal component reflects ‘arching’ or convex deformations in the dorsoventral dimension symmetrically or asymmetrically, the latter characteristic of twisting. Trends are detected in both the transverse and sagittal planes, and combinations thereof, to modify tongue shape in complex deformations. Both the transverse and sagittal components were also measured at key jaw and tongue positions, demonstrating variability particularly with respect to maximum and minimum gape. This highlights the fact that unlike tongue position, tongue deformations are more independent of jaw position, likely in response to the ever-changing bolus shape and position. From a methodological perspective, our study showcases advantages of a repeatable three-marker implant configuration suitable for animals of different sizes and highlights considerations for different implant patterns. This article is part of the theme issue ‘Food processing and nutritional assimilation in animals’.
