Which of the following is NOT a branch of the aorta in the thorax?

Correct! Wrong!

Branches of the aorta in the thorax include the posterior intercostal, bronchial, esophageal, and superior phrenic arteries

Which of the following may compress the esophagus?

Correct! Wrong!

The esophagus is compressed by the aortic arch, left main bronchus, and diaphragm

The azygos vein receives blood from which of the following?

Please select 2 correct answers

Correct! Wrong!

The azygos vein receives blood from the posterior intercostal veins, vertebral venous plexuses, mediastinal veins, esophageal veins, and bronchial veins

The hemiazygos vein does NOT receive blood from which of the following?

Correct! Wrong!

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

The accessory hemiazygos vein parallels the vertebral column along which vertebral levels?

Correct! Wrong!

The accessory hemiazygos descends on the left side of the vertebral column from T5 through T8

Which of the following is NOT contained in the anterior mediastinum?

Correct! Wrong!

The anterior mediastinum contains fat, sternopericardial ligaments, branches of internal thoracic vessels, and lymphatic vessels

Which of the following is NOT part of the sympathetic trunks?

Correct! Wrong!

The sympathetic trunk contains the superior, middle, and inferior cervical ganglia; paravertebral ganglia; and the ganglion impar

Which of the following does NOT contain synapses for the sympathetic nervous system?

Correct! Wrong!

The cardiac plexus does not contain synapses for sympathetic fibers, as these fibers have already synapsed in the sympathetic trunk

Which of the following does NOT occur in the sympathetic trunk?

Correct! Wrong!

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

Parasympathetic fibers stimulate secretion by all glands except which of the following?

Correct! Wrong!

With the exception of sweat glands, glandular secretion is parasympathetically stimulated

Vasoconstriction is sympathetically stimulated with the exception of which arteries?

Correct! Wrong!

With the exception of coronary arteries, vasoconstriction is sympathetically stimulated

Which of the following is a result of sympathetic stimulation in the heart?

Correct! Wrong!

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 a result of sympathetic stimulation in the lungs?

Correct! Wrong!

Sympathetic stimulation of the lungs results in inhibition of the parasympathetic system, bronchodilation, reduced secretion, and maximum air exchange

Sympathetic fibers of the heart are accompanied by visceral afferent fibers that convey which type of sensation?

Correct! Wrong!

Sympathetic fibers of the heart are accompanied by visceral afferent fibers, which convey pain information

The pulmonary plexus contains which of the following?

Correct! Wrong!

The pulmonary plexus contains cell bodies of postsynaptic parasympathetic fibers
