The correct Answer is:
To solve the question regarding the probable cause of the symptoms exhibited by the 35-year-old man with extremely long limbs and digits, as well as severe disfigurement of facial features, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Symptoms**: - The man has extremely long limbs and digits, which suggests a condition related to bone growth. - Severe disfigurement of facial features may indicate abnormal growth patterns in the skull or facial bones. 2. **Consider the Hormonal Options**: - The options provided are related to hormone secretion from the neurohypophysis (posterior pituitary), thyroid gland, and adrenal gland. - The hormones in question include vasopressin (ADH) and oxytocin from the neurohypophysis, thyroid hormones, and corticosteroids from the adrenal gland. 3. **Analyze Neurohypophysis Hormones**: - **Vasopressin (ADH)**: This hormone helps regulate water balance and can influence calcium levels in the body. - If there is hypersecretion of vasopressin, it could lead to increased calcium deposition in bones, potentially causing elongated limbs and digits. 4. **Evaluate Other Hormonal Options**: - **Thyroid Hormones**: Hypersecretion from the thyroid gland could lead to conditions like hyperthyroidism, which affects metabolism but does not typically cause elongated limbs. - **Corticosteroids from Adrenal Gland**: Hypersecretion leads to Cushing's syndrome, which is characterized by bone loss and not excess deposition. 5. **Conclusion**: - Given the symptoms of long limbs and digits, the most probable cause is hypersecretion of a hormone from the neurohypophysis, particularly vasopressin, which can lead to increased calcium deposition in the bones. ### Final Answer: The probable cause for the symptoms described is **hypersecretion of a hormone from the neurohypophysis (Option B)**. ---
