In decalcified bone tissue slides, which combination describes the slide preparation method and the central structure?

• A. Decalcified—Central canal
• B. Decalcified—Medullary cavity
• C. Decalcified—Volkmann's canal
• D. Ground bone—Central canal

Answer: (A)

Decalcification prepares bone so thin sections can be cut and stained, revealing the organized osteon structure. In decalcified bone, you can clearly see concentric lamellae surrounding a central canal—the Haversian canal—that runs through the center of each osteon and contains blood vessels and nerves. This central canal is the key feature highlighted in decalcified bone slides. The medullary cavity is a large internal space of the bone, not the central feature of an osteon; Volkmann's canals connect osteons but are not the central structure itself; ground bone would preserve minerals and show different details, not the decalcified central-structure focus.
