声带由不同类型组织组成,包括上皮、固有层、横纹肌、神经、血管和软骨,为多层结构,每层都有不同的作用。固有层是其中的重要结构,分为浅层、中层和深层,浅层下为任克间隙,中层主要由弹性纤维组成,而深层主要由胶原纤维组成,后两层合称声韧带。深层的深面为甲杓肌,形成声带的主 The vocal cords are made up of different types of tissues, including the epithelium, lamina propria, striated muscle, nerves, blood vessels and cartilage, and are multilayered structures that each have different roles. The lamina propria is one of the important structures, which is divided into shallow layer, middle layer and deep layer. For shallow layer, there is gap between them. The middle layer is mainly composed of elastic fibers. The deep layer is mainly composed of collagen fibers. The latter two layers are collectively called acoustic ligament. The deep deep surface of the muscular decubitus, the formation of vocal Lord
