Electromyographic (EMG) activity of six nasal muscles was monitored in 17 male volunteers without nasal complaints. Surface electrodes were placed on the nasal skin in such a way that they selectively recorded the activity of these muscles. Recordings were made under different breathing conditions and during voluntary nasal movements. Inspiratory EMG activity was observed during nasal and oral breathing in one or more of the following muscles: dilator naris, nasalis muscle (alar and transverse parts) and apicis nasi. EMG activity increased markedly in response to physical exercise and was more often present in subjects with decreased nasal patency. During voluntary nasal movements a combined activity of the six nasal muscles was consistently found. We conclude that the function of the dilator naris, the nasalis muscle and the apicis nasi strongly relates to respiration. These muscles probably contribute to the prevention of collapse of the nasal valve. The role of the procerus and levator labii superioris alaeque nasi seems to be primarily concerned with facial expression.
在17名无鼻部不适的男性志愿者中监测了6块鼻部肌肉的肌电图（EMG）活动。将表面电极置于鼻皮肤，使其能选择性记录这些肌肉的活动。在不同呼吸条件下以及自主进行鼻部运动时进行记录。在鼻呼吸和口呼吸期间，在以下一块或多块肌肉中观察到吸气EMG活动：鼻肌扩张肌、鼻肌（鼻翼部和横部）以及鼻尖肌。EMG活动在体育锻炼时显著增加，且在鼻通畅度降低的受试者中更常出现。在自主进行鼻部运动时，始终发现6块鼻部肌肉存在联合活动。我们得出结论，鼻肌扩张肌、鼻肌和鼻尖肌的功能与呼吸密切相关。这些肌肉可能有助于防止鼻瓣膜塌陷。降眉间肌和提上唇鼻翼肌的作用似乎主要与面部表情有关。
