Which of the following statements about bone remodeling and repair is correct?
A) Bone remodeling involves removal of old bone by osteoblasts.
B) As a long bone increases in diameter, the size of the marrow cavity decreases.
C) The rate of bone remodeling increases in the elderly.
D) Exposure of a bone to increased mechanical stress can lead to bone remodeling.
E) Bone remodeling does not involve the activity of the osteoclasts and the osteoblasts.

Question

Quizplus · Accepted Answer

Bone remodeling is a process that responds to mechanical stress, where the bone tissue is continuously renewed to maintain bone strength and mineral homeostasis. This process involves the activity of osteoclasts, which break down old bone, and osteoblasts, which form new bone. Increased mechanical stress stimulates this remodeling process to adapt the bone structure for better support, making option D correct.
