运动单位是骨骼肌的基本功能单位,定义为运动神经元及其相关的所有肌纤维。它们的活动代表了中枢神经系统的最终输出,它们在运动控制中的作用已被广泛研究。然而,相对较少的工作集中在不同运动任务中招募可变数量的运动单元的机械意义上。这篇综述的重点是影响整个肌肉运动单元机械输出的因素,从分子到宏观解剖成分。这些因素的范围从不同肌肉纤维类型的机械性能到构成特定类型运动单元的肌肉纤维的独特形态,以及这些运动单元纤维在肌肉内的三维排列。我们认为,由于多个层次的结构和生理组织的整合,运动单元的独特机械性能可能会出现。©2001 John Wiley & Sons, Inc中华神经科学杂志(英文版),2001
Motor units, defined as a motoneuron and all of its associated muscle fibers, are the basic functional units of skeletal muscle. Their activity represents the final output of the central nervous system, and their role in motor control has been widely studied. However, there has been relatively little work focused on the mechanical significance of recruiting variable numbers of motor units during different motor tasks. This review focuses on factors ranging from molecular to macroanatomical components that influence the mechanical output of a motor unit in the context of the whole muscle. These factors range from the mechanical properties of different muscle fiber types to the unique morphology of the muscle fibers constituting a motor unit of a given type and to the arrangement of those motor unit fibers in three dimensions within the muscle. We suggest that as a result of the integration of multiple levels of structural and physiological levels of organization, unique mechanical properties of motor units are likely to emerge. © 2001 John Wiley & Sons, Inc.
