Question 1

Which one of the following statements is incorrect ?

Accepted Answer

The pancreas contains Islets of Langerhans, which have two main types of cells: -cells and -cells. The -cells secrete the hormone glucagon, which increases blood glucose levels by stimulating glycogenolysis. The -cells secrete the hormone insulin, which decreases blood glucose levels. Therefore, the statement that -cells secrete insulin is incorrect. Answer: -cells of pancreas secrete insulin

Question 2

Match List I with List II : List I List II A. Cortisol I. Stimulates the formation of alveoli in mammary glands B. Aldosterone II. Produces anti-inflammatory reactions C. Cholecystokinin III. Stimulat

Accepted Answer

Cortisol is a glucocorticoid hormone secreted by the adrenal cortex. It produces anti-inflammatory reactions and suppresses the immune response. Aldosterone is a mineralocorticoid hormone secreted by the adrenal cortex. It acts mainly at the renal tubules and stimulates the reabsorption of Na ^ + and water. Cholecystokinin (CCK) is a gastrointestinal hormone that acts on the pancreas and gall bladder, stimulating the secretion of pancreatic enzymes and bile juice. Progesterone is a steroid hormo

Question 3

Match List-I with List-II . List-I List-II A. Excess growth hormone I. Reabsorption of water and electrolytes in kidney B. Luteinizing hormone II. Contraction of uterus during child birth C. Vasopress

Accepted Answer

Excess secretion of growth hormone in adults, especially in middle age, can result in severe disfigurement (especially of the face) called Acromegaly. Thus, A matches with III. Luteinizing hormone (LH) induces the rupture of the Graafian follicle and thereby causes the release of an ovum (ovulation). Thus, B matches with IV. Vasopressin acts mainly at the kidney and stimulates the reabsorption of water and electrolytes by the distal tubules, thereby reducing the loss of water through urine (diur

Question 4

Which of the following statements related to pituitary gland are correct ? (a) It is divided anatomically into adenohypophysis and neurohypophysis (b) It secretes follicle stimulating hormone (c) It s

Accepted Answer

The pituitary gland is anatomically divided into the adenohypophysis and the neurohypophysis. Thus, statement (a) is correct. The adenohypophysis consists of the pars distalis and the pars intermedia. The pars distalis (anterior pituitary) secretes several hormones, including Follicle Stimulating Hormone (FSH) and Prolactin (PRL). Thus, statement (b) is correct and statement (d) is incorrect. The pars intermedia secretes Melanocyte Stimulating Hormone (MSH). Thus, statement (c) is correct. There

Accepted Answer

The correct answer is [A-IV, B-II, C-I, D-III] - Progesterone - A steroidal hormone which is secreted by the corpus luteum - Relaxin - A proteinaceous hormone which is secreted by the ovaries in the later stage of pregnancy - Melanocyte stimulating hormone - A proteinaceous hormone released by the pars intermedia - Catecholamines - An amino-acid derived hormone released from the adrenal medulla during emergency conditions

Question 7

Consider the following statements regarding function of adrenal medullary hormones : (A) It causes pupilary constriction. (B) It is a hyperglycemic hormone. (C) It causes piloerection. (D) It increase

Accepted Answer

Adrenal medulla secretes two hormones called adrenaline or epinephrine and noradrenaline or norepinephrine (also called emergency hormones). Both the hormones - - Cause pupillary dilation (not constriction) - Stimulate breakdown of glycogen resulting in increased concentration of glucose in blood i.e., cause hyperglycemia. - Cause piloerection (raising of hair). - Increase strength of heart contraction i.e., heartbeat.

Question 8

Which of the following hormones released from the pituitary is actually synthesized in the hypothalamus?

Accepted Answer

Neurohypophysis i.e., posterior pituitary (Pars nervosa) stores and releases two hormones called oxytocin and vasopressin (Also called ADH i.e., antidiuretic hormone) which are actually synthesised by hypothalamus and are transported axonally to neurohypophysis. The pars distalis (anterior pituitary) produces follicle stimulating hormone (FSH), adrenocorticotropic hormone (ACTH) and luteinizing hormone (LH).

Question 9

Identify the wrong statements : A. Erythropoietin is produced by juxtaglomerular cells of the kidney B. Leydig cells produce Androgens C. Atrial Natriuretic factor, a peptide hormone is secreted by th

Accepted Answer

The correct answer is option (3), (C) and (E) only as both are wrong statements. - Atrial natriuretic factor, a peptide hormone is secreted from the atria of the heart not by the seminiferous tubules of the testes. - Gastrin acts on the gastric glands not on the intestinal wall and stimulates the secretion of hydrochloric acid and pepsinogen. Rest statements (A), (B) and (D) are correct statements. Option (1), (2) and (4) are incorrect because they have either one or two correct statements.

Accepted Answer

The correct answer is option (3) because - Epinephrine is an emergency hormone, also known as adrenaline and is secreted from adrenal medulla. - Thyroxine is secreted from thyroid gland and plays an important role in regulation of basal metabolic rate. - Oxytocin is a peptide hormone synthesised by hypothalamus and released by posterior pituitary. It causes smooth muscle contraction. - Glucagon is secreted from -cells of pancreas, acts mainly on hepatocytes and stimulates glycogenolysis resultin

Question 11

Which of the following is not a steroid hormone?

Accepted Answer

The correct answer is option (3) as glucagon is a proteinaceous hormone secreted from pancreas. Options (1), (2) and (4) are not correct as they are steroid in nature.
