Written Test SYMPHYSIS 2026 — True/False Conversion (MCQ)

Answer True (T) or False (F): Cardiac output is calculated from the product of the stroke volume and the heart rate.

• True

• False

Answer True (T) or False (F): Unique histology structure formation of muscles is shown in the heart. One of them is the twist of the rightward direction of the subepicardial layer and leftward direction of the subendothelial layer.

• True

• False

Answer True (T) or False (F): Cardiac muscle is a syncytium of many heart muscle cells in which the cardiac cells are so interconnected that when one of these cells becomes excited, the action potential spreads to all of them.

• True

• False

Answer True (T) or False (F): One of the structures of the heart is a pericardium layer made by fibrous and serous tissue, the serous tissue consists of two layered pericardium named the parietal and the visceral which are similar to epicardium.

• True

• False

Answer True (T) or False (F): The heart is composed of three major types of cardiac muscle: atrial muscle, ventricular muscle, and specialized excitatory and conductive muscle fibers.

• True

• False

Answer True (T) or False (F): The delay of conduction by AV node is done to intentionally make the ventricle contract two times.

• True

• False

Answer True (T) or False (F): The blood pressure consists of cardiac output and total peripheral resistance, while the cardiac output consists of contractility and heart rate.

• True

• False

Answer True (T) or False (F): In electrocardiogram or EKG the P wave represents the spread of depolarization through the atria and is followed by atrial contraction.

• True

• False

Answer True (T) or False (F): The heart is actually composed of two syncytiums: the atrial syncytium and the peripheral syncytium.

• True

• False

Answer True (T) or False (F): Cardiac output is obtained by dividing arterial pressure by total peripheral resistance.

• True

• False
