The histo-morphology of the arterial walls is typically made of 3 distinct layers or tunics designated as intima, media and adventitia. Based on the composition of the media, the arteries are classified into elastic and muscular types. The common iliac artery is an elastic artery, whereas its branches, the external and internal iliac arteries are muscular arteries. In this study, the presence of smooth muscle bundles outside the adventitia was noted in 93 samples taken from the iliac arterial system and the reasons for their presence have been hypothesized.
动脉壁的组织形态通常由 3 个不同的层或膜组成，分别称为内膜、中膜和外膜。根据中膜的组成，动脉可分为弹性型和肌型。髂总动脉是一种弹性动脉，而其分支，即髂外动脉和髂内动脉则是肌型动脉。在这项研究中，在髂动脉系统的 93 个样本中，在外膜外发现了平滑肌束的存在，并对其存在的原因进行了假设。
