Hypersecretion of growth hormone in adults does not cause further increase in height because
1. growth hormone becomes inactive in adults
2. epiphyseal plates close after adolescence
3. bones loose their sensitivity to growth hormone in adults
4. muscle fibres do not grow in size after birth
A temporary endocrine gland in the human body is?
1. pineal gland | 2. corpus cardiacum |
3. corpus luteum | 4. corpus allatum |
GnRH, a hypothalamic hormone, needed in reproduction, acts on the
1. anterior pituitary gland and stimulates secretion of LH and oxytocin
2. anterior pituitary gland and stimulates secretion of LH and FSH
3. posterior pituitary gland and stimulates secretion of oxytocin and FSH
4. posterior pituitary gland and stimulates secretion of LH and relaxin
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 |
