Which of the following tissues is defined by its ability to increase tension and contract?

A. Femur:The femur (especially the femoral neck) is a common site of osteoporotic hip fractures but not the single most frequent site overall.
B. Vertebrae:Vertebral bodies are frequently weakened by osteoporosis and commonly fracture, leading to compression fractures and height loss.
C. Humerus:The proximal humerus can fracture with osteoporosis but is less commonly affected than vertebrae and hip.
D. Tibia:The tibia is a strong weight-bearing bone and is a less typical primary site for osteoporosis-related fragility fractures.

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.
