• B. Posterior lobe of the pituitary
• C. Adrenal gland
• D. Gonads

Answer 1

Answer: (A)

Anterior lobe of the pituitary

GH is the growth hormone, secreted by the anterior pituitary, which targets soft tissues and bones and serves to stimulate cell division, protein synthesis and bone growth. Posterior pituitary gland does not secrete any hormone; vasopressin and oxytocin are produced by hypothalamus but stored and released into the bloodstream via posterior pituitary. Adrenal gland secretes glucocorticoids, mineralocorticoids, sex hormones (by adrenal cortex) and epinephrine and norepinephrine (by the adrenal medulla. Gonads (testes and ovaries) secrete androgens and estrogen and progesterone respectively. Thus, the correct answer is option A.
