A. | Parathyroid hormone | I. | Flight or fight response |
B. | Epinephrine and Nor-epinephrine | II. | Regulates the body's biological clock |
C. | Thyroid stimulating hormone | III. | Increases blood \(\)Ca2+ level |
D. | Melatonin | IV. | Synthesis of \(\text{T}_3~ \text{and} ~\text{T}_4\) hormones |
Normal sleep-wake cycle in a human body is maintained by the secretion of:
1. Thyroid gland
2. Thymus gland
3. Pineal gland
4. Pituitary gland
Artificial light, extended work-time and reduced sleep-time disrupt the activity of:
1. Thymus gland
2. Pineal gland
3. Adrenal gland
4. Posterior pituitary gland
A temporary endocrine gland in the human body is:
1. | Corpus cardiacum | 2. | Corpus luteum |
3. | Corpus allatum | 4. | Pineal gland |
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. |
The 24-hours (diurnal) rhythm of our body such as the sleep-wake cycle is regulated by the hormone:
1. melatonin
2. calcitonin
3. prolactin
4. adrenaline
Melatonin is secreted by:
1. Pineal gland
2. Skin
3. Pituitary Gland
4. Thyroid
