Quizplus · Accepted Answer

Growth hormone is of greatest importance for bone growth during infancy and childhood. It stimulates the liver and other tissues to produce insulin-like growth factor 1 (IGF-1), which in turn stimulates bone growth. Parathyroid hormone, calcitonin, and thyroid hormones play important roles in regulating calcium levels in the blood and bone remodeling, but do not have as significant of an impact on bone growth during infancy and childhood.
