A) Weakness in the muscular wall of an artery
B) Impaired synthesis of clotting factors
C) Deficits in the autonomic control of blood pressure
D) Increased levels of cerebrospinal fluid
Ans: A
Feedback:
Aneurysms are direct manifestations of a weakness that exists in the muscular wall of an arterial vessel. Hypertension is a significant risk factor, but autonomic contributions are not common. Levels of cerebrospinal fluid (CSF) and hypo- or hypercoagulability are not implicated in the pathogenesis of aneurysms.
