Correct! Wrong!

The fibrous pericardium is attached to the posterior surface of the sternum by the sternopericardial ligaments

All of the following veins drain into the coronary sinus EXCEPT

Correct! Wrong!

The coronary sinus receives the great and small cardiac veins, middle cardiac vein, left posterior ventricular vein, and left marginal vein. The anterior cardiac veins begin over the anterior surface of the right ventricle and cross over the coronary groove to end directly in the right atrium

The SA node, a small collection of nodal tissue and specialized cardiac muscle fibers, is the pacemaker of the heart. The SA node is supplied by a branch of the right coronary artery in about 60% of individuals

Correct! Wrong!

The levatores costarum are innervated by the dorsal primary rami of C8–T11

Which of the following do NOT elevate the ribs?

Correct! Wrong!

The serratus posterior inferior depresses the ribs

With which of the following does the intercostobrachial nerve communicate?

Correct! Wrong!

The intercostobrachial nerve communicates with the medial brachial cutaneous nerve

Anterior and posterior intercostals arteries pass between which two layers?

Correct! Wrong!

The musculophrenic artery gives rise to anterior intercostal arteries for intercostal spaces 7–9

Anterior and posterior intercostals arteries pass between which two layers?

Correct! Wrong!

Anterior and posterior intercostal arteries pass between the internal and innermost intercostal muscles

Of the bronchopulmonary segments in the superior lobe of the left lung, which two are combined to form the lingula?

Correct! Wrong!

The superior and inferior bronchopulmonary segments of the superior lobe of the left lung combine to form the lingula

Which of the following areas do NOT receive visceral afferent fibers?

Correct! Wrong!

Visceral afferent fibers are distributed to bronchial mucosa, bronchial muscles, interalveolar connective tissue, and pulmonary arteries and veins

Sympathetic nerves do NOT contribute to which of the following?

Correct! Wrong!

The diaphragm receives somatic efferent and afferent innervation—not sympathetic innervation

Which of the following is correct?

Correct! Wrong!

While a person is supine, the arch of the aorta lies superior to the transverse thoracic plane
