What are the three structures located inside the carotid sheath?
The internal jugular Vein, the common carotid Artery, and the vagus Nerve (remember the Mnemonic VAN)
What is the spatial relationship among the three structures located inside the carotid sheath?
The internal jugular vein is lateral, the common carotid artery is medial, and the vagus nerve is posterior
An enlarged left atrium can cause which noncardiac symptoms?
Dysphagia due to compression of the esophageal nerve and hoarseness due to compression of the recurrent laryngeal nerve
What is the most posterior part of the heart?
The left atrium
Which coronary artery is most commonly occluded?
The left anterior descending artery, which supplies the interventricular septum
In what part of the cardiac cycle do the coronary arteries fill?
In most cases, the sinoatrial and atrioventricular nodes are supplied by which coronary artery?
The right coronary artery
The right coronary artery supplies the posterior septum via which coronary artery?
The posterior descending artery
If the right coronary artery supplies the inferior portion of the left ventricle via the posterior descending artery is the heart right or left dominant?
A patient has a myocardial infarction that damages the anterior interventricular septum and the apex. Which coronary artery was occluded?
The left anterior descending artery
The posterior descending artery that supplies the posterior septum arises from the circumflex artery in _____ (20%/50%/80%) of cases.
