Which one of the following hormones is not involved in sugar metabolism?
1. Cortisol
2. Aldosterone
3. Insulin
4. Glucagon
Which one of the following hormones though synthesised elsewhere, is stored and released by the master gland?
1. Melanocyte-stimulating hormone
2. Antidiuretic hormone
3. Luteinizing hormone
4. Prolactin
A chemical signal that has both endocrine and neural roles is:
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 blood pressure. |
Fight - or - flight reaction cause activation of:
1. | the parathyroid glands, leading to increased metabolic rate. |
2. | the kidney, leading to suppression of the rennin angiotensin-aldosterone pathway. |
3. | the adrenal medulla, leading to increased secretion of epinephrine and norepinephrine |
4. | the pancreas leading to a reduction in blood sugar levels. |
1. | Organs in the body like the gastrointestinal tract, heart, kidney and liver do not produce any hormones. |
2. | Non-nutrient chemicals produced by the body in trace amount that act as intercellular messengers are known as hormones. |
3. | Releasing and inhibitory hormones are produced by the pituitary gland. |
4. | Adenohypophysis is under direct neural regulation of the hypothalamus. |
Select the answer which correctly matches the endocrine gland with the hormone it secretes and its function/deficiency symptom:
Endocrine gland | Hormone | Function/deficiency symptom | |
(1) | Posterior Pituitary | Growth Hormone (GH) | Oversecretion stimulates abnormal growth |
(2) | Thyroid gland | Thyroxine | Lack of iodine in diet results in goitre |
(3) | Corpus luteum | Testosterone | Stimulates spermatogenesis |
(4) | Anterior pituitary | oxytocin | Stimulates uterus contraction during childbirth |
1. (1)
2. (2)
3. (3)
4. (4)
Endocrine gland | Hormone | Functions | |
1. | Placenta | estrogen | initiates secretion of milk |
2. | Corpus luteum | estrogen | essential for the maintenance of endometrium |
3. | Leydig cells | androgen | initiates the production of sperm |
4. | Ovary | FSH | stimulates follicular development and the secretion of estrogens |
