The unit containing osteons and Haversian canals is part of which tissue type?

• A. Spongy bone
• B. Cortical bone
• C. Hyaline cartilage
• D. Dense connective tissue

Answer: (B)

Osteons, or Haversian systems, are the organizing units of compact bone—the dense, outer layer of bone tissue. Each osteon features concentric lamellae arranged around a central Haversian canal that houses blood vessels and nerves, providing a strong, well-supplied structure. Spongy bone is made of trabeculae and lacks osteons; hyaline cartilage is avascular and does not contain Haversian canals; dense connective tissue is a broad category that includes bone as a specialized form, but the distinctive unit containing osteons and Haversian canals is found in cortical (compact) bone.
