Pineal gland of human brain secretes melatonin, which is concerned with Sleep Anger Colouration of skin Body temperature None 16. When the blood phosphorus level becomes too high, the result is The thyroid gland releases calcitonin, which binds to bone cells. The thyroid gland releases thyroid hormone, which binds to small intestine cells The pancreas release glucagon, which binds to liver cells The parathyroid glands release PTH, which binds to bone cells. None 17. What role is performed by pancreas in order to deal with an increased blood glucose level above normal range? Releases glucagon, signaling adipose cells to take up glucose Releases glucagon, signaling muscle cells to take up glucose Releases insulin, signaling the liver to convert glucose to glycogen Releases insulin, signaling muscle cells to release glucose None 18. Thyroid hormone increase the rate of breathing, intake and consumption of oxygen, and increase the activity of mitochondria. Under which of the following criteria, the function of thyroxine can be classified? Cardiovascular Developmental Metabolic All of the above None 19. The pineal gland secretes a hormone progesterone which helps to regulate sleep pattern. Thyroid glands release hormone which regulate the level of calcium in the blood with the help of calcitonin which is produced in the parathyroid glands. Select the correct option regarding the given paragraph.i) Positions of pineal and parathyroid should be interchangedii) Progesterone must be replaced by melatoniniii) Parathyroid should not be replaced as it is correctly mentioned.iv) Positions of progesterone and calcitonin should be interchangedv) Positions of thyroid and parathyroid should be interchanged ii and iv only i, ii and v only ii and v only i and iii only None 20.
