d) Cortisol

e) A and B

e) C and D

Answer 1

Ans.1 (B) epinephrine

Epinephrine is the principal hormone secreted by the adrenal medulla, although it also releases some norepinephrine. The adrenal medulla, the inner part of an adrenal gland, controls hormones that initiate the flight or fight response. The main hormones secreted by the adrenal medulla include epinephrine (adrenaline)

Ans.2 (e) both a and b

Part of adrenal medulla, producing excessive amounts of nor- epinephrine and epinephrine, which are constantly or paroxysmally secreted into the blood stream, causing tachycardia, hypertension and other symptoms. in this diseases, Heart-related conditions such as high blood pressure (hypertension).

Poor blood supply to the heart muscle due to coronary artery disease (atherosclerosis), heart valve disease, heart failure, heart muscle disease (cardiomyopathy), tumours, or infections.

Ans.3. (b) cortisol

Level of adrenocorticotropic hormone release then adrenocorticotropic hormone reaches the adrenal glands, it binds on to receptors causing the adrenal glands to secrete more cortisol, resulting in higher levels of cortisol in the blood.
