Hyperfunctioning of thyroid glands will cause:
Correct answer: C. Loss of body weight
- A. Enlargement of bones
- B. Slow heart rate and nervousness
- C. Loss of body weight
- D. Sexual precocity
Explanation
Hyperthyroidism happens when the thyroid gland makes too much thyroid hormone. This condition also is called overactive thyroid. Hyperthyroidism speeds up the body's metabolism. Typical symptoms of hyperthyroidism are weight loss, fast heart rate, high irritability/nervousness, muscle weakness and tremors, infrequent menstrual periods, sleep problems, eye irritations, and heat sensitivity. Hence option c (loss of body weight) is the only correct symptom that matches with the symptoms stated above.

About Chemical Coordination and Hormones
Chemical coordination uses hormones released by endocrine glands and carried in blood to specific target cells. Coverage includes the pituitary, thyroid, pancreas, adrenal glands, ovaries and testes, feedback control, and the contrast between slower, longer-lasting hormonal responses and rapid nervous coordination.
