Question #47392
The Question
A 45-year-old patient presents with severe facial disfigurement and spinal complications due to a functional adenoma in the pars distalis. Which of the following statements correctly describes the impact of this endocrine dysfunction on the patient's axial skeleton?
Options
- A.
The patient will exhibit a significant increase in height due to accelerated interstitial growth of the C7, T12, L5, S(1), C(1) vertebrae.
- B.
The genetically fixed vertebral formula remains C7, T12, L5, S(1), C(1), but the vertebrae undergo abnormal appositional growth leading to deformities.
- C.
Hypersecretion of somatostatin from the hypothalamus induces the de-ossification and fusion of the existing 26 vertebrae.
- D.
The vertebral formula shifts to accommodate new bone formation, increasing the total number of bones in the axial skeleton beyond 80.

Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: Distinguishing between interstitial bone growth (pre-pubertal lengthening) and appositional bone growth (post-pubertal thickening) under GH influence.
Common Misconception: Students often confuse the effects of Gigantism with Acromegaly, assuming 'bone growth' always implies an increase in height or the addition of new bones, failing to realize that the genetic blueprint (vertebral formula) remains strictly constant despite severe morphological plasticity.
