Question

In adult human beings, growth and cell division stop in __________.

• A. Skin cells
• B. Bone marrow
• C. Testes and ovary
• D. Bone cells

Answer 1

The correct option is D Bone cells

Bone tissues are continuously remodeled through the concerted actions of bone cells. These include bone resorption by osteoclasts and bone formation by osteoblasts. On the other hand, osteocytes act as mechanosensors and orchestrators of the bone remodeling process. This process is under the control of local and systemic factors in the adult human. These all together contribute to bone homeostasis. Also, in adult human beings, growth and cell division stop in the bone cells. This is not happening in skin cells and bone marrow. Option D is correct.
