GnRH, a hypothalamic hormone, needed in reproduction, acts on
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
Changes in GnRH pulse frequency in females is controlled by circulating levels of:-
(1) estrogen and inhibin
(2) progesterone only
(3) progesterone and inhibin
(4) estrogen and progesterone
Which of the following pairs of hormones are not antagonistic (having opposite effects) to each other?
1. Insulin Thyroid hormone
2. Aldosterone Atrial Natriuretic Factor
3. Relaxin Inhibin
4. Parathormone Calcitonin
Which one of the following hormones is not involved in sugar metabolism?
1. Cortisone
2. Aldosterone
3. Insulin
4. Glucagon
Which one of the following hormones though synthesised elsewhere, is stored and
released by the master gland?
1. Antidiuretic hormone
2. Luteinizing hormone
3. Prolactin
4. Melanocyte stimulating hormone
A chemical signal that has both endocrine and neural roles is
(1) melatonin
(2) calcitonin
(3) epinephrine
(4) cortisol
Fight or flight reactions cause activation of
1. the parathyroid glands, leading to increased metabolic rate
2. the kidney, leading to suppression of reninangiotensin-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
