The contraction times of the cat's tongue muscles were measured by recording the fine movements of their surfaces and movements of the tongue's surfaces. The recordings were made by means of a commercial, high-sensitive light reflection transducer (Fairchild FPLA 850) which could be operated without any mechanical loading of the tongue. The contraction times of the intrinsic muscles (including pars longitudinalis superior m. hypoglossi and pars longitudinalis inferior m. styloglossi) measured about 22 ms, while the extrinsic muscles were somewhat slower, around 33 ms. The data are considered in the light of the recently reported histochemical composition of these muscles. The study of the hypoglossal nerve supply to individual tongue muscles revealed that, contrary to earlier reports, the medial nerve sends branches to the intrinsic muscles not only at its distal end but during its entire course through the tongue. The transversal and vertical muscles were found to receive numerous fibers innervating small units of their muscle fibers.
通过记录猫舌肌表面的精细运动和舌面的运动来测量猫舌肌的收缩时间。记录是通过一个商用的高灵敏度光反射换能器（仙童FPLA 850）进行的，该换能器在不对舌头施加任何机械负荷的情况下即可操作。舌内肌（包括舌下肌上纵部和茎突舌肌下纵部）的收缩时间约为22毫秒，而舌外肌的收缩时间稍慢，约为33毫秒。根据最近报道的这些肌肉的组织化学组成对这些数据进行了分析。对支配单个舌肌的舌下神经供应的研究表明，与早期报告相反，内侧神经不仅在其远端，而且在其贯穿舌头的整个行程中都向舌内肌发送分支。发现横肌和垂直肌接受许多支配其肌纤维小单元的纤维。
