Which of the following is NOT a movement that can occur between vertebrae?

Choice A reason: Granulation tissue forms early in the healing process, not after the bony callus. It precedes the formation of fibrocartilaginous and bony calluses.

Choice B reason: Remodeling of the bony callus is the correct answer. After the bony callus forms, it is gradually reshaped by osteoclasts and osteoblasts to restore the bone’s original structure and strength.

Choice C reason: The fibrocartilaginous callus forms before the bony callus, serving as a temporary bridge between broken bone ends.

Choice D reason: Hematoma formation is the initial step in fracture healing, occurring immediately after injury.

Choice E reason:

Choice A reason: Central lamellae is not a recognized anatomical term. The central canal, however, is part of an osteon and contains blood vessels and nerves. It does not refer to lamellae between osteons.

Choice B reason: Concentric lamellae are rings of bone matrix that surround the central canal within an osteon. They are integral to the osteon structure and not found between osteons.

Choice C reason: Circumferential lamellae are located around the outer and inner surfaces of compact bone, encircling the entire bone structure. They are not found between osteons.

Choice D reason: Perforating canals, or Volkmann’s canals, run perpendicular to the central canals and connect them to the periosteum and medullary cavity. They are not lamellae and do not lie between osteons.

Choice E reason: Interstitial lamellae are remnants of old osteons that have been partially resorbed during bone remodeling. They fill the spaces between current osteons and are not part of any single osteon, making them the correct answer.
