Exophthalmia is a classic symptom of:
Correct answer: A. Hyperthyroidism
- A. Hyperthyroidism
- B. Hypocalcemia
- C. Hypochondria
- D. Hypercalcemia
Explanation
Exophthalmia, the abnormal protrusion of the eyes, is typically associated with Graves' disease, a form of hyperthyroidism. This condition arises when the thyroid gland produces excessive thyroxine, leading to metabolic imbalances and symptoms such as increased heart rate and weight loss. Exophthalmia occurs due to the buildup of tissue behind the eyes, a common feature in Graves' disease.In contrast, hypocalcemia and hypercalcemia are conditions related to abnormal calcium levels in the blood, with distinct symptoms unrelated to eye protrusion. Hypochondria is a psychological condition involving health anxiety, not a physical symptom like exophthalmia.

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.
