Question: 11
11. A disorder of the pineal gland would most likely result in which of the following disorders?
- A. High blood pressure
- B. Diabetes
- C. Insomnia
- D. Hyperthyroidism
Correct Answer: C
Explanation:
The pineal gland is responsible for producing melatonin, which controls the body's circadian rhythm. Insomnia would be a disturbance of this circadian rhythm, and may be attributable to a pineal gland disorder in some cases. Hypertension, diabetes, and hyperthyroidism would be unrelated to issues with the pineal gland.
