What is the role of growth hormones related to bone health?

• A. They inhibit bone formation
• B. They stimulate division of cartilage cells
• C. They decrease calcium absorption
• D. They restrict osteoclast activity

Answer: (B)

Growth hormones play a crucial role in bone health by stimulating the division of cartilage cells, particularly within the growth plate of bones. This process is essential for the longitudinal growth of bones, especially during childhood and adolescence. By promoting the proliferation of chondrocytes or cartilage cells, growth hormones facilitate the development and elongation of bones, which is vital for achieving proper skeletal size and structure.

This action also indirectly influences bone density and strength, as healthy cartilage contributes to the ongoing processes of bone remodeling and formation. The stimulation of cartilage cell division by growth hormones leads to the creation of an adequate bone matrix, promoting the overall health of the skeletal system.

Thus, the correct answer emphasizes the positive role of growth hormones in supporting bone health through their direct effect on cartilage cells, highlighting their importance in normal growth and development.
