Question

Which of the following statements is false?

a. Polyphagia, dysuria and hypoglycemia are all symptoms associated with insulin deficiency.
b. hGH carries out its roles by the actions of insulin-like growth factors.
c. The hormones of the adrenal medulla mimic the action of sympathetic nerves.
d. The parathyroid glands secrete PTH which increase serum calcium, this hormone is antagonistic to calcitonin which decreases calcium levels in the blood.
e. Both ADH and aldosterone tend to lead to water retention and elevation of BP

Answer 1

The false statement is 'a,' as hypoglycemia is not associated with insulin deficiency; insulin deficiency leads to hyperglycemia. Other statements regarding hormone functions and interactions are accurate.

Step-by-step explanation:

The false statement is letter a: Polyphagia, dysuria, and hypoglycemia are all symptoms associated with insulin deficiency. This statement is false because hypoglycemia is not a symptom of insulin deficiency. Instead, insulin deficiency typically leads to hyperglycemia, which is high blood glucose levels. In conditions like diabetes mellitus, where insulin activity is low, one would expect to see increased blood sugar, not decreased.

Regarding the other statements, human growth hormone (hGH) indeed works through insulin-like growth factors, the hormones of the adrenal medulla do mimic the action of sympathetic nerves, and the parathyroid hormone (PTH) is antagonistic to calcitonin in regulating serum calcium levels. Both ADH and aldosterone promote water retention and can elevate blood pressure, making these statements true.
