三维(3D)舌头运动是哺乳动物和其他四足动物完成摄食功能的核心，但人们对摄食过程中的3D舌头运动学知之甚少。用双平面摄像技术记录了猕猴在咀嚼葡萄时的舌头运动。舌头在咀嚼过程中复杂的形状变化是由舌头在矢状面上的弯曲和绕其长轴的滚动共同控制的。根据人类的假设，在猕猴的舌头回缩过程中，舌头的中部(磨牙区)滚动到咀嚼(工作)侧，同时向矢状面弯曲，而舌尖则弯曲到另一边(平衡)。扭转和屈曲在咀嚼周期的快速关闭阶段早期达到最大值，在动力冲刺之前将食物团定位在接近的牙齿之间。虽然3D舌头运动学无疑会随着食物类型的不同而不同，但这种运动的机械作用--将食物块放在尖牙后的牙齿上以供分解--可能会在咀嚼周期的这个阶段对舌头运动学产生强大的制约。这些运动的肌肉驱动力可能包括内在和外在舌肌的组合。
Three-dimensional (3D) tongue movements are central to performance of feeding functions by mammals and other tetrapods, but 3D tongue kinematics during feeding are poorly understood. Tongue kinematics were recorded during grape chewing by macaque primates using biplanar videoradiography. Complex shape changes in the tongue during chewing are dominated by a combination of flexion in the tongue's sagittal planes and roll about its long axis. As hypothesized for humans, in macaques during tongue retraction, the middle (molar region) of the tongue rolls to the chewing (working) side simultaneous with sagittal flexion, while the tongue tip flexes to the other (balancing) side. Twisting and flexion reach their maxima early in the fast close phase of chewing cycles, positioning the food bolus between the approaching teeth prior to the power stroke. Although 3D tongue kinematics undoubtedly vary with food type, the mechanical role of this movement—placing the food bolus on the post-canine teeth for breakdown—is likely to be a powerful constraint on tongue kinematics during this phase of the chewing cycle. The muscular drivers of these movements are likely to include a combination of intrinsic and extrinsic tongue muscles.
