Consider the following statements regarding function of adrenal medullary hormones : (A) It causes pupilary constriction. (B) It is a hyperglycemic hormone. (C) It causes piloerection. (D) It increases strength of heart contraction. Choose the correct answer from the options given below :

Step-by-step solution

Adrenal medulla secretes two hormones called adrenaline or epinephrine and noradrenaline or norepinephrine (also called emergency hormones). Both the hormones - - Cause pupillary dilation (not constriction) - Stimulate breakdown of glycogen resulting in increased concentration of glucose in blood i.e., cause hyperglycemia. - Cause piloerection (raising of hair). - Increase strength of heart contraction i.e., heartbeat.
