Question

Which of the following endocrine glands doesn't work under regulation of pituitary gland :-
a- parathyroid
b- Thyroid gland
c- Adrenal cortex
d- Adrenal medulla
e- Testis / ovary
(1) a and b
(2) a and d
(3) b, c and e
(4) a, d and e

Answer 1

Thyroid gland is controlled by thyroidstimulating hormone (TSH), which is produced by the pituitary gland. Corticosteroids are produced by the adrenal cortex. Its secretion is regulated by the adrenocorticotropic hormone from the anterior pituitary. Testis and ovaries produce sex hormones, which are controlled by FSH and LH of the pituitary gland.
At the same time, parathyroid and adrenal medulla produce hormones independently from the pituitary.
Thus, the answer 2 (a and d) is correct.
