Graves' disease is caused due to?
1. hyposecretion of thyroid gland
2. hypersecretion of thyroid gland
3. hyposecretion of adrenal gland
4. hypersecretion of adrenal gland
Name a peptide hormone which acts mainly on hepatocytes, adipocytes and enhances cellular glucose uptake and utilisation.
1. Insulin
2. Glucagon
3. Secretin
4. Gastrin
The posterior pituitary gland is not a ‘true’ endocrine gland because
1. it is provided with a duct
2. it only stores and releases hormones
3. it is under the regulation of hypothalamus
4. it secretes enzymes
Which one of the following hormones is not involved in sugar metabolism?
1. Cortisone
2. Aldosterone
3. Insulin
4. Glucagon
Identify the hormone with its correct matching of source and function.
1. Oxytocin-posterior pituitary, growth and maintenance of mammary glands
2. Melatonin-pineal gland, regulates the normal rhythm of sleep-wake cycle
3. Progesterone-corpus luteum, stimulation of growth and activities of female secondary sex organs
4. Atrial natriuretic factor-ventricular wall increases the blood pressure
Fight or flight reactions cause activation of
1. | the parathyroid glands, leading to increased metabolic rate |
2. | the kidney, leading to suppression of renin-angiotensin-aldosterone pathway |
3. | the adrenal medulla, leading to increased secretion of epinephrine and norepinephrine |
4. | the pancreas leading to a reduction in the blood sugar levels |
Which of the following statement is correct in relation to the endocrine system?
1. | Adenohypophysis is under direct neural regulation of the hypothalamus |
2. | Organs in the body like gastrointestinal tract, heart, kidney and liver do not produce any hormones |
3. | Non-nutrient chemicals produced by the body in trace amount that act as intercellular messenger are known as hormones |
4. | Releasing and inhibitory hormones are produced by the pituitary gland |
Select the answer which correctly matches the endocrine gland with the hormone it secretes and its function/deficiency symptom
Endocrine gland | Hormone | Function/deficiency symptoms | |
1. | Anterior pituitary | Oxytocin | Stimulates uterus contraction during child birth |
2. | Posterior pituitary | Growth Hormone (GH) | Over-secretion stimulates abnormal growth |
3. | Thyroid gland | Thyroxine | Lack of iodine |
4. | Corpus luteum | Testosterone | Stimulates spermatogenesis |
Which one of the following pairs of hormones are the examples of those that can easily pass through the cell membrane of the target cell and bind to a receptor inside it (mostly in the nucleus)?
1. Insulin and glucagon
2. Thyroxine and insulin
3. Somatostatin and oxytocin
4. Cortisol and testosterone
Match the source gland with its respective hormone as well as the function.
Source gland | Hormone | Function | |
1. | Posterior pituitary | Vasopressin | Stimulates resorption of water in the distal tubules in nephron |
2. | Corpus luteum | Oestrogen | Supports pregnancy |
3. | Thyroid | Thyroxine | Regulates blood calcium level |
4. | Anterior pituitary | Oxytocin | Contraction of uterus muscles during child birth |
