Innervation of the epithelium on the undersurface of the canine vocal cords was investigated by transmission electron microscopy. In the subepithelial lamina propria, nerve bundles containing unmyelinated fibers were observed. The nerve bundles, encircled by basal lamina, were enclosed by a thin connective tissue layer and by flattened fibroblast-like cells. With nerve bundles approaching the epithelium, the axons divided repeatedly and entered the epithelial layer. In the epithelial cells, nerve axons formed knob-like swellings that contained a small number of large granular vesicles and a large number of small agranular vesicles. A sensory function responsive to irritant chemical stimuli and to mechanical stimuli is presumed for these vesicle-containing nerve processes.
通过透射电子显微镜对犬类声带下表面上皮的神经支配进行了研究。在上皮下固有层中，观察到含有无髓纤维的神经束。这些神经束被基膜环绕，由一层薄的结缔组织层和平扁的成纤维细胞样细胞包裹。随着神经束接近上皮，轴突反复分支并进入上皮层。在上皮细胞中，神经轴突形成了含有少量大颗粒囊泡和大量小无颗粒囊泡的球状膨大。推测这些含有囊泡的神经突起具有对刺激性化学刺激和机械刺激的感觉功能。
