Anatomy of Cardiovascular System
THE CARDIOVASCULAR SYSTEM
[1]
On a front direct projection of the thorax X-ray the expansion of the left contour of the middle shadow in its lower department is present. What department of the heart is enlarged?
A. Auricle of the left atrium
B. Right ventricle
C. Left atrium
D. Right atrium
E. Left ventricle
The middle shadow on a front direct projection of the thorax X-ray is formed by the heart and vessels diverging from it. The middle shadow of left contour is formed by four arches. The most superior one is a shadow of the aorta’s arch and its divergent vessels, lower – the pulmonary trunk, then the left auricle and the most inferior one is the left ventricle.
[2]
In a 45-year-old patient the myocardial infarction of the front wall of the left ventricle and interventricular septum is diagnosed, which is accompanied by disturbance of cardiac rhythm. What components of the heart conductive system are disturbed?
A. Sinoatrial node
B. Atrioventricular bundle
C. Atrioventricular node
D. Left peduncle of the atrioventricular bundle
E. Right peduncle of the atrioventricular bundle
The heart conductive system is formed by nodes located inside the atrium walls and of bundles connecting these nodes and passing through the interventricular septum as an atrioventricular bundle conducting an electric impulse to myocardium of ventricles.
[3]
A 65-year-old patient was addmitted to the hospital with complaints of pain and disturbance of cardiac rhythm. After examination the diagnosis of blockade of Hiss bundle was made. What formation of the heart is it located in?
A. In the cusps of the mitral valve
B. In the interatrial septum
C. In the cusp of the tricuspid valve
D. In the interventricular septum
E. On the heart apex
Hiss bundle (or atrioventricular bundle) is a part of heart conductive system. It diverges from atrioventricular node, then it goes to iterventricular septum, then divides into two crura following to ventricle myocardium.
