The musculus uvulae and the levator veli palatini muscle were studied with electromyography (EMG) in three normal young adult subjects. Patterns of EMG activity for the musculus uvulae were similar to those of the levator veli palatini for all three subjects. When differences in EMG activity between the two muscles were found, the tasks did not involve speech. The presence of the musculus uvulae along the nasal aspect of the velum may be important in filling the space between the elevated velum and the posterior pharyngeal wall. In addition, the musculus uvulae may function to modify stiffness of the tissue adjacent to the insertion of the levator veli palatini and to produce extension of the velum.
对三名正常年轻成年人的悬雍垂肌和腭帆提肌进行了肌电图（EMG）研究。三名受试者的悬雍垂肌肌电活动模式与腭帆提肌相似。当发现两块肌肉之间的肌电活动存在差异时，这些任务并不涉及言语。悬雍垂肌沿腭帆鼻侧的存在可能对填充抬高的腭帆与咽后壁之间的间隙很重要。此外，悬雍垂肌可能起到改变腭帆提肌附着处相邻组织的硬度并使腭帆伸展的作用。
