目的：在以往的研究中，对软腭肌神经支配的描述因作者而异。本研究通过对软腭咽神经丛和腭小神经的分布进行解剖学研究，以重新认识软腭肌的神经支配。结果：腭帆提肌和腭咽肌受腭小神经和咽丛分支的双重支配，结论：软腭位于腭小神经分布区与咽丛分布区的交界处。这可能是为什么在以前的研究中存在争议的软腭肌肉的神经支配。
Objective: Descriptions of the innervation of the soft palate muscles in previous studies have varied according to the author. In the present study, distribution of the lesser palatine nerve, through which motor fibers of the facial nerve are considered to reach soft palate muscles, and that of the pharyngeal plexus in the soft palate were investigated in order to reexamine the innervation of the soft palate muscles according to anatomical evidence.Results: Observations suggested that the levator veli palatini and palatopharyngeus were doubly innervated by branches of the lesser palatine nerve and pharyngeal plexus, and that the musculus uvulae was innervated by only the lesser palatine nerve.Conclusion: The soft palate is considered to be located in the border region between the areas of distribution of the lesser palatine nerve and pharyngeal plexus. This may be why controversies exist in previous studies about the innervation of the soft palate muscles.
