Which of the following is NOT a branch of the right coronary artery?
The branches of the right coronary artery include the SA nodal, right marginal, posterior interventricular, and AV nodal arteries
Which of the following is NOT a branch of the aorta in the thorax?
Branches of the aorta in the thorax include the posterior intercostal, bronchial, esophageal, and superior phrenic arteries
Which of the following is NOT contained in the anterior mediastinum?
The anterior mediastinum contains fat, sternopericardial ligaments, branches of internal thoracic vessels, and lymphatic vessels
Sympathetic fibers of the heart are accompanied by visceral afferent fibers that convey which type of sensation?
Sympathetic fibers of the heart are accompanied by visceral afferent fibers, which convey pain information
Parasympathetic fibers stimulate secretion by all glands except which of the following?
With the exception of sweat glands, glandular secretion is parasympathetically stimulated
The thymus is supplied by which of the following?
The thymus is supplied by the anterior intercostal and anterior mediastinal branches of the internal thoracic artery
The pulmonary plexus contains which of the following?
The pulmonary plexus contains cell bodies of postsynaptic parasympathetic fibers
Which of the following does NOT occur in the sympathetic trunk?
In the synaptic trunk, presynaptic neurons synapse with postsynaptic neurons immediately. Some fibers ascend and synapse, while other fibers descend and synapse. Some fibers pass into a splanchnic nerve without synapsing
Which of the following may compress the esophagus?
The esophagus is compressed by the aortic arch, left main bronchus, and diaphragm
The hemiazygos vein does NOT receive blood from which of the following?
The hemiazygos vein receives blood from the left subcostal vein, ascending lumbar veins, the inferior three posterior intercostal veins, inferior esophageal veins, and small mediastinal veins
Which of the following does NOT contain synapses for the sympathetic nervous system?
The cardiac plexus does not contain synapses for sympathetic fibers, as these fibers have already synapsed in the sympathetic trunk
The accessory hemiazygos vein parallels the vertebral column along which vertebral levels?
The accessory hemiazygos descends on the left side of the vertebral column from T5 through T8
Vasoconstriction is sympathetically stimulated with the exception of which arteries?
With the exception of coronary arteries, vasoconstriction is sympathetically stimulated
Which of the following is NOT a result of sympathetic stimulation in the lungs?
Sympathetic stimulation of the lungs results in inhibition of the parasympathetic system, bronchodilation, reduced secretion, and maximum air exchange
The pericardium does NOT receive blood supply from which of the following?
The pericardium receives blood supply from the pericardiacophrenic artery, musculophrenic artery, bronchial arteries, esophageal arteries, superior phrenic arteries, and coronary arteries
Which of the following is NOT contained in the superior mediastinum?
The superior mediastinum contains the thymus, great vessels and their branches, vagus nerves, phrenic nerves, cardiac plexus, left recurrent laryngeal nerve, trachea, esophagus, thoracic duct, and prevertebral muscles
Which of the following is a result of sympathetic stimulation in the heart?
Sympathetic stimulation of the heart increases the rate and strength of contraction and inhibits the effect of the parasympathetic system on coronary arteries, allowing them to dilate
Which of the following is NOT part of the sympathetic trunks?
The sympathetic trunk contains the superior, middle, and inferior cervical ganglia; paravertebral ganglia; and the ganglion impar
