Consider the given two statements:
I: | Catecholamines, Adrenaline, and Noradrenaline, are called emergency hormones or hormones of Fight or Flight. |
II: | They are rapidly secreted in response to stress of any kind and during emergency situations. |
1. Both I and II are correct and II explains I
2. Both I and II are correct but II does not explain I
3. I is correct but II is incorrect
4. Both I and II are incorrect
Glucagon is a hyperglycaemic hormone. All the following are effects of this hormone except:
1. Gluconeogenesis
2. Glycogenesis
3. reduced cellular glucose uptake and utilization
4. glycogenolysis
Hormones that interact with membrane-bound receptors, do not enter the target cell but generate second messengers which in turn regulate cellular metabolism. An example of such a hormone would be:
1. Adrenocorticotrophic hormone
2. Triiodothyronine
3. Progesterone
4. Cortisol
Hormonal control of the secretion of digestive juices is carried out by local hormones produced by the gastric mucosa and intestinal mucosa. Which of the following hormones stimulates gall bladder to contract?
1. gastrin
2. cholecystokinin
3. secretin
4. gastric inhibitory peptide
Identify the correctly matched pair:
Part of the pituitary | Hormone synthesized | |
I: | Pars distalis | Gonodotropin releasing hormone |
II: | Pars intermedia | Melanocyte stimulating hormone |
III: | Pars nervosa | ADH and oxytocin |
1. | Only III | 2. | Only II |
3. | Only I and II | 4. | Only II and III |
Both cortisol and insulin:
I. favour protein anabolism
II. Cause proteolysis
III. Reduce the uptake of amino acids by the body cells
1. Only I and II are correct
2. Only I and II are correct
3. I, II and III are correct
4. I, II and III are incorrect
Dwarfism can be caused by the deficiency, during childhood, of:
I. | Growth hormone |
II. | Thyroid hormones |
1. | Only I and the dwarf will have normal mental development |
2. | Only II and the dwarf will also be mentally retarded |
3. | Both I and II and in both cases the mental development will be affected |
4. | Both I and II and mental development will be effected only in II. |
Match each item in Column I with one in Column II and select the correct match from the codes given:
Column I | Column II | ||
A. | Heart | P. | Synthesis of angiotensinogen |
B. | Lungs | Q. | Secretion of atrial natriuretic peptide |
C. | Kidneys | R. | Primary site for conversion of angiotensin I to angiotensin II |
D. | Liver | S. | Secretion of renin |
A | B | C | D | |
1. | P | Q | R | S |
2. | R | Q | P | S |
3. | Q | R | S | P |
4. | Q | R | P | S |

2. is responsible for regulating the body's daily (circadian) clock
3. is the pneumotaxic centre
4. is the thermostat of the human body
Assertion (A): | Oxytocin helps in parturition and causes milk ejection from the mammary glands. |
Reason (R): | Oxytocin acts on the smooth muscles of our body and stimulates their contraction. |
1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
3. | (A) is True but (R) is False. |
4. | Both (A) and (R) are False. |
