Osteology – II

Osteology – II

These advanced questions cover detailed aspects of bone biology, genetics, and physiology, providing a deeper understanding of osteology.

1 / 10

Which cytokine, produced by osteoblasts, is essential for the differentiation and activation of osteoclasts and is often targeted in treatments for osteoporosis?

2 / 10

Osteoarthritis is primarily characterized by the degradation of which type of cartilage found in synovial joints?

3 / 10

Which of the following growth factors is most critical in the initial stages of fracture healing and stimulates the recruitment and proliferation of mesenchymal stem cells?

4 / 10

What is the primary mineral component of bone, providing it with its hardness and strength?

5 / 10

Which hormone, produced by the thyroid gland, lowers blood calcium levels by inhibiting osteoclast activity and stimulating calcium excretion by the kidneys?

6 / 10

Which protein, produced by osteoblasts, binds to RANKL and inhibits osteoclastogenesis, thereby reducing bone resorption?

7 / 10

During endochondral ossification, which zone of the growth plate is characterized by the proliferation of chondrocytes and increased cell division?

8 / 10

The condition characterized by the excessive breakdown and formation of bone tissue, leading to bone pain, deformities, and fractures, is known as:

9 / 10

The process by which bone adapts to mechanical loading, often described by Wolff’s law, involves which type of bone cell?

10 / 10

Mutations in the gene coding for the protein “collagen type I” are most commonly associated with which genetic bone disorder?
