Question

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. Submit

Answer 1

Answer:

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:

As per the question, the effects of tumors like pheochromocytoma in the inner part of medulla may lead to several problems as the number of hormones secreted are too high in the adrenal gland which leads to complications. It results in extended events that are quite identical to the sympathetic nervous system, like inflated heart rate as well as blood pressure. Along with that, it also leads to a decreased level of digestion as well as urinary actions and an elevated metabolic rate which could be fatal as it increases the chances of a stroke, attack, etc. Therefore, option C is the correct answer.
