TOPIC 1: MYOCARDIAL STRUCTURE AND FUNCTION
14 Questions • 9.7% of Exam • Explores the anatomy and physiology of the heart muscle and its role in cardiovascular health.
QUESTION 1
Myocardium
Correct Answer: Heart muscle that surrounds ventricles and atrium Atria are thinner as they need to pump
less strong.
Rationale: The statement is correct because the myocardium refers to the thickest layer of the heart wall, and it is indeed
the layer that surrounds both the ventricles and atria, providing the necessary support for pumping blood throughout the
body. The atria are thinner because they receive blood and pump it into the ventricles, requiring less force compared to the
ventricles, which need to pump blood throughout the entire body, making the ventricular walls thicker.
QUESTION 2
Pericardium
Correct Answer: External layer that protects heart from injury/infection.
Rationale: The pericardium serves as a protective external layer because it encloses the heart and surrounding structures,
forming a sac that prevents external factors such as bacteria, physical damage, and excessive pressure from causing harm.
This protective function is essential in maintaining the heart's integrity and facilitating its proper functioning.
QUESTION 3
Blockage of coronary arteries can lead to
Correct Answer: Heart attack or stroke.
Rationale: A blockage of coronary arteries disrupts blood flow to the heart, leading to oxygen deprivation and potential
damage to the heart
muscle. This disruption of blood flow, if severe and prolonged, can cause a heart attack, and if the blockage occurs in the
arteries that supply blood to the brain, it can lead to a stroke.

QUESTION 4
Cardiomegaly
Correct Answer: Abnormal enlargement of the heart due to over working to compensate for decreased
function.
Rationale: Cardiomegaly refers to the condition where the heart becomes enlarged due to an increase in workload, often
resulting from decreased cardiac function, requiring the heart to pump harder and expand to compensate for the reduced
efficiency. This adaptation ultimately leads to the characteristic abnormal enlargement of the heart, making cardiomegaly a
critical indicator of underlying heart conditions.
QUESTION 5
Normal heart sounds
Correct Answer: S1 and S2.
Rationale: The correct answer "S1 and S2" refers to the first and second heart sounds, which are the two primary sounds
produced by a normal heart during its cardiac cycle. These sounds occur due to the closure of the heart valves, specifically
the mitral and tricuspid valves closing to produce S1, and the aortic and pulmonary valves closing to produce S2.
QUESTION 6
S2 heart sound
Correct Answer: Occurs with closure of aortic and pulmonic valves (semilunar valves)
-"dub" sound
-loudest at base of heart (2nd intercostal space)
Rationale: The second heart sound (S2) occurs with closure of the aortic and pulmonic valves due to the elastic recoil of
these semilunar valves after they open to allow blood to leave the ventricles, producing a distinct "dub" sound. This sound is
loudest at the base of the heart in the 2nd intercostal space because the aortic and pulmonic valves are located near this
area, allowing for optimal transmission of the sound.
