The adrenal medulla secretes epinephrine and norepinephrine. A tumor on the adrenal medulla, called pheochromocytoma, causes excess amounts of these two hormones to be secreted. The effects of this type of tumor would lead to: a) prolonged events like the parasympathetic nervous system, such as decreased digestive functions, increased urination, slowed heart rate and pupil dilation. b) prolonged events like the sympathetic nervous system, such as sexual arousal, increased salivation, urination, and digestive functions. c) prolonged events similar to the sympathetic nervous system, such as elevated heart rate and blood pressure, decreased digestive and urinary activities and increased metabolic rate. d) prolonged events like the parasympathetic nervous system, such as increased sweating, heartrate, and blood flow to the limbs.

c) prolonged events similar to the sympathetic nervous system, such as elevated heart rate and blood pressure, decreased digestive and urinary activities and increased metabolic rate.

Explanation:

The adrenal medulla secretes epinephrine and norepinephrine. A tumor on the adrenal medulla, called pheochromocytoma, causes excess amounts of these two hormones to be secreted. The effects of this type of tumor would lead to prolonged events similar to the sympathetic nervous system, such as elevated heart rate and blood pressure, decreased digestive and urinary activities and increased metabolic rate.

The medulla manages the fight-or-flight response through the release of epinephrine and norepinephrine. norepinephrine functions by increasing heart rates which causes the release of more glucose and increased supply of oxgenated blood to various parts of the body while epinephrine is concerned with the increased supply of sugar. This are sympathetic functions. An increase in the secretion of both will result in a prolonged  increased heart rate, blood pressure and metabolic rate in response to stress management.
