弹性纤维是一种主要存在于结缔组织中的细胞外间质成分 ,由成纤维细胞、平滑肌细胞、某些软骨细胞等产生 ,赋予所在器官 (如皮肤、肺、动脉、黄韧带、耳廓软骨等 )以良好的弹性。在形态学上弹性纤维的结构很简单 ,光镜下呈现为分支成网的细丝状 ,直径介于 0 2～ 1 0 μｍ。电 Elastic fibers, an extracellular matrix component mainly found in connective tissue, are produced by fibroblasts, smooth muscle cells, certain chondrocytes and the like and give organs, such as the skin, lungs, arteries, ligamentum flavum, auricular cartilage Etc.) with good flexibility. Morphology of the elastic fiber structure is very simple, under the light microscope showed branched filaments, diameter between 0 2 ~ 1 0 μm. Electricity
