By use of actomyosin ATPase histochemistry, it was found that there were large differences among the three cat infrahyoid muscles (sternohyoid, sternothyroid, and thyrohyoid) with respect to their percentages of different muscle fiber types. It has been established that the individual activity patterns of the component motor units in each muscle drive the biochemical and physiologic differentiation of the muscle fibers associated with each motor unit. Therefore, the data obtained in the present investigation provide an indication of the characteristics of long-term use of each of the various types of motor units, as well as the associated differences in the physiologic capacities of the different motor unit types composing each of these infrahyoid muscles.
通过肌动球蛋白ATP酶组织化学方法发现，猫的三块舌骨下肌（胸骨舌骨肌、胸骨甲状肌和甲状舌骨肌）在不同肌纤维类型的百分比方面存在很大差异。已经确定，每块肌肉中组成运动单位的个体活动模式驱动着与每个运动单位相关的肌纤维的生化和生理分化。因此，本研究获得的数据表明了各种类型运动单位的长期使用特征，以及构成这些舌骨下肌中每一块肌肉的不同运动单位类型在生理能力上的相关差异。
