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
