Which bone cell type is primarily responsible for bone resorption, and what clinical condition might excessive activity lead to?
Osteoblasts; osteopetrosis
Osteoclasts; osteoporosis
Osteocytes; osteoporosis
Chondrocytes; osteoarthritis
The Correct Answer is B
A. Osteoblasts; osteopetrosis: Osteoblasts build bone matrix and excessive activity leads to denser bone, not osteopetrosis, which involves defective bone resorption.
B. Osteoclasts; osteoporosis: Osteoclasts break down bone tissue during remodeling; when their activity outweighs bone formation, it can result in osteoporosis due to bone loss.
C. Osteocytes; osteoporosis: Osteocytes maintain the bone matrix and act as mechanosensors but do not perform resorption that causes bone thinning.
D. Chondrocytes; osteoarthritis: Chondrocytes maintain cartilage tissue, and their degeneration contributes to osteoarthritis rather than affecting bone resorption.
