Structural Properties of Human Cerebral Arteries as Assessed by a Constituent-Based Biomechanical Model

Human cerebral arteries may develop aneurysms, as a result of geometrical and structural modifications in the arterial wall resulting from a variety of genetic, epigenetic and biomechanical factors. Aneurysms exhibit a markedly different wall composition and structure, characterized by relatively low elastin content as shown in Figure 1.
