Which statement best describes long bones?

• A. Shorter than they are wide
• B. Longer than they are wide
• C. Equal length and width
• D. Curved

Answer: (B)

Long bones are bones that are longer than they are wide, built to act as levers for movement and to support body weight. Their elongated shaft (the diaphysis) and two ends (the epiphyses) shape how they work in movement and force transmission. Because length is their defining feature, they are much longer than they are wide, which is why the statement describing them as longer than they are wide is the best fit. Examples include the femur and humerus. Shorter-than-wide would describe non-long bones like carpals; equal length and width would describe roughly cube-shaped bones; curvature can occur in many bones but doesn’t define long bones.
