(a) The hormone produced by adrenal medulla.
(b) The condition caused by the over secretion of insulin.
(c) The hormone secreted by beta cells of the islets of Langerhans.
(d) The interconnection between the two lobes of thyroid gland (technical term).
(e) The hormone whose under secretion causes more urine formation.
(f) The hormone which stimulates the entire sympathetic nervous system.
Ans:
(a) Adrenaline
(b) Hypoglycemia
(c) Insulin
(d) Isthmus
(e) Anti-diuretic hormone (Vasopressin)
(f) Adrenaline
Que-2: What would a child suffer from, if there was hypo secretion from his thyroid?
Ans:
If there was hyposecretion of the thyroid gland in a child; the child will suffer from cretinism. The symptoms of cretinism are dwarfism, mental retardation, etc.
Que-3: Choose the odd one out from each series and write the category of the remaining terms:
(a) Simple goitre, Cretinism, Pellagra, Myxoedema
(b) Alpha cells, Beta cells, Gamma cells, Delta cells
(c) Somatotropin, Prolactin, Oxytocin, Luteinizing hormone
(d) Thyroid, Pituitary, Prostate, Parathyroid
(e) Thyroxine, Insulin, Thiamine, Glucagon
Ans:
(a) Odd term: Pellagra
Category: Diseases caused due to hypothyroidism
(b) Odd term: Gamma cells
Category: Islet of Langerhans
(c) Odd term: Oxytocin
Category: Hormones secreted by anterior part of pituitary gland
(d) Odd term: Prostate
Category: Endocrine glands
(e) Odd term: Thiamine
Category: Hormones
Que-4: Write full forms of the following abbreviations:
(a) ACTH
(b) TSH
(c) ADH
(d) LH
(e) FSH
Ans:
(a) ACTH: Adrenocorticotropic Hormone
(b) TSH: Thyroid Stimulating Hormone
(c) ADH: Antidiuretic Hormone
(d) LH: Luteinizing Hormone
(e) FSH: Follicle Stimulating Hormone
Que-5: Identify the odd one in each of the following and mention what the rest are:
(a) Larynx; glucagon; testosterone; prolactin
(b) Adrenaline; penicillin; insulin; thyroxine
(c) Stomach; ileum; liver; adrenaline
(d) TSH; GH; ADH; insulin
(e) Iodine; cretinism; goitre; myxoedema
Ans:
(a) Larynx is the odd one out because glucagon, testosterone, and prolactin are hormones, while the larynx is the voice box.
(b) Penicillin is the odd one here because adrenaline; insulin; thyroxine are hormones whereas Penicillin is an antibiotic.
(c) Adrenaline is the odd one here because stomach, ileum and liver are the organs of the digestive system whereas Adrenaline is a hormone.
(d) Insulin is the odd one here because TSH, GH, ADH are the hormones secreted by the pituitary gland whereas Insulin is secreted by the pancreas.
(e) Iodine is the odd one out because cretinism, goitre, and myxoedema are diseases caused by low secretion of thyroxine, while iodine is needed to make thyroxine.
Que-6: Match the terms given in column A with those in column B.
| Column A | Column B |
|---|---|
| (a) Adrenaline | (i) Hypoglycemia |
| (b) Adrenal virilism | (ii) Hyperglycemia |
| (c) Addison’s disease | (iii) Mental retardation |
| (d) Acromegaly | (iv) Eyes are protruded |
| (e) Cushing’s syndrome | (v) Excessive growth of bones in face |
| (vi) Emergency hormone | |
| (vii) Masculine characters |
Ans:
| Column A | Column B |
|---|---|
| (a) Adrenaline | (vi) Emergency hormone |
| (b) Adrenal virilism | (vii) Masculine characters |
| (c) Addison’s disease | (i) Hypoglycemia |

| (e) Cushing’s syndrome | (ii) Hyperglycemia |
Que-7: Given below are group of terms. In each group the first pair indicates the relationship between the two terms. Suggest the suitable word(s) for the fourth place.
(a) Beta cells : Insulin : : Alpha cells : ………………….
(b) Children : Cretinism : : Adults : ………………….
(c) Undersecretion : Dwarfism : : Oversecretion : ………………….
(d) Diabetes mellitus : Insulin : : Diabetes insipidus : ………………….
Ans:
(a) Beta cells : Insulin : : Alpha cells : Glucagon.
(b) Children : Cretinism : : Adults : Myxoedema.
(c) Undersecretion : Dwarfism : : Oversecretion : Gigantism.
(d) Diabetes mellitus : Insulin : : Diabetes insipidus : Antidiuretic hormone (ADH).
