用８只犬实验并观察了环杓后肌、环杓侧肌和杓肌对环构关节的驱动作用。环构后肌收缩使杓状软骨外翻跨动，同时沿环构关书面向外侧滑动，导致声带突向后、外、上方旋转，两侧杓状软骨相互远离，声门开大；构斜肌除能协助声带突外展之外，还能有效地遏制声带突上旋，从而避免了声门开大过程中声带后部过分上抬。环杓侧肌收缩使杓状软骨内翻跨动，声带突向前、内、下方旋转，膜间部声门闭合；杓横肌收缩除能使两侧构状软骨向内侧滑动相互靠拢而关闭软骨间部声门之外，尚能借助于构状软骨内侧面阻止声带突下旋，从而使声门闭合时声带后部不致出现下移。
Eight dogs were used to test the driving effects of circumferior circumferior, circumflex lateralis and ladle muscles on the circumflex joint. Circumclusal muscle contraction so that the arytenoid cartilage ectopic translocations, along with the ring structure off the book to the outside slide, leading to the vocal cords protruding to the outside, top rotation, both sides of the arytenoid cartilage away from each other, glottis opened large; In addition to assisting the vocal cord to highlight the outreach, but also effectively prevent the vocal cords sudden supination, so as to avoid excessive glottal open vocal cords in the process of excessive lifting. Contraction of the side of the dipper pelvis so that the arytenoid cartilage varus across the vocal fold to the front, the inner and lower rotation, intergranular glottic closure; dipper transverse muscle contraction can make both sides of the shape of the cartilage sliding closer to each other and closed Cartilage outside the glottic, still with the help of the inner surface of the cartilage structure to prevent the pronation process of pronation, so that when the glottis closed the back of the vocal cords will not appear down.
