咬肌是功能异质性的，具有由多个肌腱和多羽状排列的肌纤维组成的复杂结构。在这项研究中，兔咬肌的解剖分区的基础上，肌腱的起源和插入，一般分区方向相对于颧弓，运动终板的描述，和主要的神经分支，支配这些分区。这项工作完善了以前的描述，兔咬肌，并描述了13个解剖分区，每个都有一个独特的肌腱附件。此外，14个自然发生的主要神经分支被确定，并发现支配肌肉的不同区域。在将解剖分区和相关的神经支配模式相关联之后，确定了简单的分支顺序将不足以定义兔咬肌中的所有神经肌肉隔室。
The masseter muscle is functionally heterogeneous with a complex architecture consisting of multiple tendons and a multipennate arrangement of muscle fibers. In this study, the anatomical partitioning of the rabbit masseter is described on the basis of the tendons of origin and insertion, general partition orientation relative to the zygomatic arch, motor endplate descriptions, and primary nerve branches that innervate these partitions. This work refines previous descriptions of the rabbit masseter and describes 13 anatomical partitions, each with a unique tendinous attachment. In addition, 14 naturally occurring primary nerve branches were identified and found to innervate different regions of the muscle. After correlating the anatomical partitions and the associated neural innervation pattern, it was determined that simple branch order will not adequately define all the neuromuscular compartments in the rabbit masseter.
