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.
Endemic goitre is a state of
normal thyroid function
moderate thyroid function
increased thyroid function
decreased thyroid function
Steroid hormones work as
They enter into target cells and binds with specific receptor and ativate4s specific genes to form protein
They bind to cell membrane
They catalyse formation of cAMP
None of the above
Which of the following hormone secretes a gastric secretion?
Entero gastrone
Gastrin
CCK-PZ
Villikinin
During the propagation of a nerve impulse, the action potential results from the movement of
K+ ions from extracellular fluid to intracellular fluid
Na+ ions from intracellular fluid to extracellular fluid
K+ ions from intracellular fluid to extracellular fluid
Na+ ions from extracellular fluid to intracellular fluid
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
Adrenaline and noradrenaline are hormones that act as
Energy producing agents
Food storage materials
Neurotransmitters
Energy storing substances
