617 Questions
Endocrine and metabolic disorders focus on diseases caused by hormonal imbalances, such as goitre, diabetes mellitus, and hyperthyroidism. Test takers will find questions related to disease causes, diagnostic tests like Cushing's syndrome indicators, and clinical treatments. This is a crucial biology topic frequently asked in medical entrance and public service commission examinations.

Endocrine and Metabolic Disorders Questions
-
Goitre
-
Thyroid
-
Pellagra
-
None of the Above
A
Correct answer
Explanation
Iodine deficiency causes goitre, a condition characterized by abnormal enlargement of the thyroid gland in the neck. The thyroid requires iodine to produce hormones, and when iodine is insufficient, the gland enlarges to compensate. Thyroid is the gland itself (not the disease), Pellagra is caused by niacin (B3) deficiency, making Goitre the correct answer.
-
Graves disease
-
Schleroderma
-
Alopecia areata
-
Hashimoto's thyroiditis
C
Correct answer
Explanation
Alopecia areata is an autoimmune condition causing excessive hair loss throughout the body. It results from the immune system attacking hair follicles. Graves disease and Hashimoto's thyroiditis affect the thyroid, while scleroderma affects connective tissue.
B
Correct answer
Explanation
Thyroup contains levothyroxine, which is a synthetic thyroid hormone used to treat hypothyroidism (underactive thyroid), not hyperthyroidism. Therefore, the statement is false.
A
Correct answer
Explanation
The pituitary gland regulates growth hormone production. In children, excessive growth hormone causes gigantism, while insufficient production leads to dwarfism. This demonstrates the pituitary's critical role in growth and development.
B
Correct answer
Explanation
Type 2 diabetes is characterized by insulin resistance - the body's cells don't respond properly to insulin. This is different from Type 1 diabetes, which is an autoimmune condition where the pancreas produces little or no insulin.
-
Pancreas
-
Lungs
-
Liver
-
Intestines
A
Correct answer
Explanation
Diabetes is a metabolic disorder involving insulin production and regulation. The pancreas is the organ responsible for producing insulin, which regulates blood sugar levels. While diabetes affects the whole body, the pancreas is the primary organ involved in its pathophysiology.
-
Muscles
-
Forehead
-
Spine
-
Thyroid Gland
D
Correct answer
Explanation
Goitre is the abnormal enlargement of the thyroid gland, located in the neck. It is often caused by iodine deficiency. The thyroid gland (option D) is the correct answer, not muscles, forehead, or spine.
-
Goiter
-
Dysentery
-
Bronchitis
-
Asthma
A
Correct answer
Explanation
A goiter is the medical term for swelling in the neck caused by an enlarged thyroid gland. This condition can result from iodine deficiency, autoimmune disorders, or other thyroid dysfunctions. Dysentery affects the intestines, bronchitis is lung inflammation, and asthma is a respiratory condition.
-
Goitre
-
Scurvy
-
Obesity
-
Immediate Death
A
Correct answer
Explanation
Iodine deficiency causes Goitre (enlarged thyroid gland), as iodine is essential for thyroid hormone production. Scurvy is caused by Vitamin C deficiency, and Obesity is not caused by micronutrient deficiency. Iodine is crucial for metabolism regulation.
-
Uric Acid
-
Glucose
-
Cholesterol
-
Calcium
B
Correct answer
Explanation
Hyperglycemia means abnormally high blood glucose levels, typically above 126 mg/dL when fasting or 180 mg/dL after meals. This condition is a hallmark of diabetes mellitus. The prefix hyper- means elevated or excessive, while glycemia refers to sugar concentration in blood.
-
Retarded growth
-
Weakening of bones
-
Increased height
-
None of the above
C
Correct answer
Explanation
Excessive secretion of growth hormone (GH) from the pituitary gland during childhood causes gigantism, resulting in significantly increased height. In adults, this causes acromegaly (bone thickening), but in children, it leads to abnormal vertical growth.
-
Simple goitre
-
Cretinism
-
Dwarfism
-
Mental redardation
-
Tetany
E
Correct answer
Explanation
Deficiency of calcitonin causes tetany.
-
Thyroxin : Myxedema
-
Parathormone : Hypocalcemia
-
Androgens : Adrenal virilism
-
Diabetes insipidus : Glucose
-
Thyroxin : Exophthalmic goitre
D
Correct answer
Explanation
The correct pair is diabetes insipidus : Water.
-
salt
-
glucose
-
insulin
-
glucagon
-
all of these
B
Correct answer
Explanation
Diabetes mellitus is a condition in which the pancreas no longer produces enough insulin therefore by drinking water more frequently diabetic person and urinate frequently as their bodies try to get rid of the extra glucose.
