Multiple Choice QuestionsWhich of the following is an amino acid derived hormone?
Epinephrine
Ecdysone
Estriol
Estradiol
A.
Epinephrine
Epinephrine is derived from tyrosine amino acid by the removal of the carboxyl group. It is a catecholamine.
Which of the following gastric cells indirectly help in erythropoiesis?
Chief cells
Mucous cells
Parietal cells
Goblet cells
C.
Parietal cells
Parietal or oxyntic cell is a source of HCl and intrinsic factor. HCl converts iron present in diet from ferric to ferrous form so that it can be absorbed easily and used during erythropoiesis.
Intrinsic factor is essential for the absorption of vitamin B12 and its deficiency causes pernicious anaemia.
Hypersecretion of Growth Hormone in adults does not cause further increase in height, because
Growth Hormone becomes inactive in adults
Epiphyseal plates close after adolescence
Bones loose their sensitivity to Growth Hormone in adults
Bones loose their sensitivity to Growth Hormone in adults
B.
Epiphyseal plates close after adolescence
Epiphyseal plate is responsible for the growth of bone which close after adolescence so hypersecretion of growth hormone in adults does not cause further increase in height.

Anterior pituitary gland and stimulates secretion of LH and oxytocin
Anterior pituitary gland and stimulates secretion of LH and FSH
Posterior pituitary gland and stimulates secretion of oxytocin and FSH
Posterior pituitary gland and stimulates secretion of oxytocin and FSH
B.
Anterior pituitary gland and stimulates secretion of LH and FSH

A decrease in blood pressure/volume will not cause the release of
Renin
Atrial Natriuretic Factor
Aldosterone
Aldosterone
B.
Atrial Natriuretic Factor
A decrease in blood pressure / volume stimulates the release of renin, aldosterone, and ADH while increase in blood pressure / volume stimulates the release of Atrial Natriuretic Factor (ANF) which cause vasodilation and also inhibits RAAS (Renin Angiotensin Aldosterone System) mechanism that decreases the blood volume/pressure.
