she feels her heart is going to explode - zkadhem
#1
Question 1 of 2
A middle-aged woman describes flushing, severe headaches, and a feeling that her heart is "going to explode" when she gets excited. At the beginning of a physical examination her blood pressure (130/85) is not significantly above normal. However, on palpation of her upper left quadrant, the examining physician notices the onset of sympathetic signs. Her blood pressure (200/135) is abnormally high. A subsequent CT scan confirms the suspected tumor of the left adrenal gland. The patient is scheduled for surgery.

The symptoms that the patient correlated with the onset of excitement were due to nervous stimulation of the adrenal glands. The adrenal medulla receives its innervation from which of the following nerves?
A.Preganglionic sympathetic nerves
B.Postsynaptic sympathetic nerves
C.Preganglionic parasympathetic nerves
D.Postganglionic parasympathetic nerves
E.Somatic nerves

Adrenal meduula is endocrine galnd, the postsynaptic sympathetic ganglion are modified into chromaffin granules

so the answer here is presynaptic sympathetic nerves

The answer is: A

The adrenal medulla is innervated from thoracic levels of the spinal cord mediated by preganglionic sympathetic nerve fibers traveling in the lesser and least splanchnic nerves, with some contribution from the greater splanchnic and lumbar splanchnic nerves. Because both the adrenal medulla and postganglionic sympathetic neurons are adrenergic and derived from neural crest tissue, the homology of the chromaffin cells and postganglionic sympathetic neurons is apparent. There appears to be no parasympathetic innervation to the adrenal medulla and no innervation whatever to the adrenal cortex.

Yes, it is A. For clarification:
