1 Endocrine GLANDS: Question:1 Fill in the Blanks. 1. Hormones are secreted by endocrine glands which are poured in to the blood. 2. Adrenal medulla secretes adrenaline hormone which prepares the body to meet any emergency situation. 3. Pancreas as a ductless gland, has special groups of hormone secreting cells called as islets of langehers 4. Glucocoricioidss co regulates carbohydrates, protein and fat metabolism. 5. Thyroid Gland is a bilobed structure situated in front of the neck just below the larynx. 6. Cretinism is a condition which effects the growth of children showing dwarfism and mental retardation. 7. Over secretion of the growth hormone in an adult results in. Acromegaly. 8. Deficiency of ant diuretic hormone causes diabetes insipid diseases. 9. Pituitary gland popularly called the master gland. 10. The full form of A C T H is.( Adrenocosticotropic hormone) 11. Pituitary gland stimulates growth and stimulates secretion of hormones from other glands. 12. Oxytocin stimulates contraction of uterus during labour. 13. The two lobes of thyroid gland are joined by gigantism. 14. Thyroxine regulates basal metabolism. 15. The cause of diabetes mellitus deficiency in insulin. 16. The structure which controls the master gland hypothalamus. 17. The disease cased by iodine deficiency Goitre. 18. The hormone secreted by thyroid gland thyroxin. 19 The hormone secreted by the beta cells of pancreas insulin. 20. A hormone that controls basal metabolic rate. Thyroxin. 21. Lack of iodine in the diet causes Goitre. 22. Adrenaline is produced y inner medullary part of adrenal gland. 23. Insulin makes the liver turn blood sugar into Glycogen. 24. Endocrine glands are ductless glands glands possess ducts Stimulates the secretion of thyroxine Hormone stimulates ovulation in females. 28. Prolactin is secreted by The two lobes of thyroid gland are connected by a mass of tissue called the controls the absorption of glucose in the body. Question:2 Answer whether the following statements are true or false 1. Hormones are extremely important secretions for the regulation of body activities. (T). 2. Adrenalin is called fight ad flight hormone (T) 3. Mineralocosticoids regulates mineral metabolism specially Na+ sk + ions (T)

2 4. Glucagon stimulates liver to convert glycogen in to glucose. (T) 5. Insulin is secreted from alpha cells (F) 6. Thyroid secretes two hormones i.e. Thyroxine & calcitonin (T) 7. Simple goiter is the enlargement of the thyroid gland and is visible as a swelling in the neck. (T) 8. Growth hormone stimulates vigorous contractions of the uterus in a pregnant mother Leading to the birth of the baby (orytocin) 9.) Vasopressin secreted by anterior lobe controls reabsorption of water from kidney tubules (F) 10) Simple goiter can be prevented by using iodized salt in food. (T) 11. Thyroid stimulating hormone is secreted by the anterior lobe of pituitary gland. (T) 12. Pituitary gland is also called the master gland. (T) 13. The pituitary gland is both exocrine andendocrine 14. Incorporation of idone in to table salt may reduce the incidence of simple goiter.(t) 15. The failure of estrogens result in eunuchoidism of urine.(f) 16. Vasopressin is related with the concentration of urine. (T) 17. A hormone responsible for puberty in male is testosterone.(t) 18. Prolactin stimulates milk ecretion and grouth of brest. (T) 19. Myxedema is caused due to malfunctioning of thyroid gland. (T) 20. Thyroid gland secretes adrenalin.(f) 21. Hormones are chemically proteins. (T) 22. Hormones act as biocatalysis. 13. Vasopressin is an antidiuretic hormone. 14. Glucagon is a catabolic hormone. 15. Hormones are poured in to the arterial blood. 16. Lack of insulin results in diabetes insipidus. 17. TSH or thyrotropin stimulates the secretion of thyroxine by thyroid gland. 18. Cretinism is a congenital disorder. 19. The adrenal glands are located on the superior surface of each kidney. 20. The endocrine portion of pancreas consists of groups of cells called islets of Calleja. Question 3 Chose the correct answer from the choices given in the bracket;- 1. Hypo secretion from adrenal cortex causes (Addison s disease, cushings Syndrome, Obesity, none of the above) 2. Insufficient secretion of insulin causes. ( Diabetes mellitus, diabetes insipidus, Insulin shock, None of the above) 3. over secretion of thyroxin causes. ( Simple goiter, exophthelmic goiter, myxoede, none of the above)

3 4) Cortex and medulla are the two regions of. ( Adrenal gland, Thyroid gland, Pituitary gland, none of the above) 5. The deficiency of Growth Hormone in childhood results in (Dwarfism, gigantism, Acromegaly, none of the above) 6. A gland having Endocrine as well as exocrine function is. (Pituitary, Thyroid, Pancreas, adrenal) 7. Pituitary gland weighs about. (2 grams, 3 grams, one half gram, 5 grams) 8. Chemically, some hormones are. (Minerals, Vitamins, Proteins, none of the above) 9. The hormone that is not secreted by Pituitary gland. ( GH, TSH, ACTH, Cortisone) 10 The hormone concerned with facing dangers is. (Thyroxine, cortisone, Adrenalin, none of the above) Question: 4 Select the term that does not fit in to the group 1. Goitre, dwarfism, acromegaly, cataract. (hormonal diseases) 2. ADH, TSH, NADP, ACTH. (hormones) 3. Steroids, cortisone, testosterone, adrenalin (hormones) 4. Adrenal, liver, thyroid, pituitary. (endocrine glands) 5. Adrenalin, penieillin, insulin, thyroxine (hormones) 6. Vasopressin, growth hormone, TSH, ACTH. (anterior lobe of pituitary) 7. Thyroid, adrenal, pituitary, prostrate. 8. Cretinism, myxedema, goiter, scurvy. 9. Insulin, glucagons, diabetes, Mellitus. 10. Insulin, blood sugar, adrenalin, thyroxine. 11.
