弹性纤维是动脉壁的主要成分之一，对动脉弹性纤维知识的熟悉有助于了解在动脉移植过程中或影响弹性纤维的疾病过程中一，血管弹性纤维的适应性改变。采用8条狗的股动脉，置人88％甲酸，45C环境下消化96小时后，用扫描电镜观察。内膜中的弹性纤维以内弹性膜的方式出现，膜上有许多大小不一的窗孔散布。膜的腔面光滑，外面有纤维与中膜的弹性组织相连。中膜弹性纤维粗细不一，互相交织朝各个方向排列，形成连续的网样结构。外膜是弹性纤维集中之处，它们以不完整的板状形式出现，呈同心圆排列成7－8层，这种同心圆排列的弹性纤维板层主要由宽大的纵行纤维组成，它们之间有细的横纤维相连，同心圆板层之间也有细纤维连接。内弹性膜将管腔内压力均匀传递给中膜，并能防止导致动脉粥样硬化的大分子通过，营养物质可通过窗孔弥散到中膜。中膜弹性网将营腔内传递来的及中膜平滑肌主动收缩产生的力向四周传递。外膜对维持血管的弹性起重要作用，由于它以宽大的纵行纤维为主，所以主要传递纵向张力。
Elastic fibers are one of the main components of the arterial wall. Knowledge of arterial elastic fibers is helpful to understand the adaptive changes of the elastic fibers in the process of arterial transplantation or the diseases that affect the elastic fibers. Using 8 dog femoral artery, placed 88% formic acid, 45C environment after 96 hours of digestion, with scanning electron microscopy. Elastic fibers in the intima appear in the form of an inner elastic membrane with numerous pores of different sizes interspersed. The lumen of the membrane is smooth, and the outer fibers are connected with the elastic tissue of the middle membrane. Median elastic fibers vary in thickness, intertwined with each other in all directions arranged to form a continuous network-like structure. The outer membrane is the elastic fiber concentration, they appear in the form of an incomplete plate, concentric circles arranged in 7-8 layers, this concentric circular elastic fiber layer is mainly composed of large longitudinal fibers, between them There are thin cross-linked fibers, there are also fine fiber connections between the concentric layers. The inner elastic membrane evenly transmits the pressure in the lumen to the middle membrane and prevents the passage of macromolecules leading to atherosclerosis. The nutrients can diffuse into the middle membrane through the windows. Mesh elastic mesh will be delivered to the camp and the smooth muscle contraction of the media produced by the force to the surrounding transmission. The adventitial membrane plays an important role in maintaining the elasticity of blood vessels. Since it is mainly composed of broad longitudinal fibers, it mainly transmits longitudinal tension.
