Verified step by step guidance

Step 1: Understand the anatomy of compact bone. Compact bone is organized into structures called osteons, which are cylindrical units containing a central canal (Haversian canal) surrounded by concentric lamellae.

Step 2: Learn the function of perforating canals (Volkmann's canals). These canals run perpendicular to the central canals and serve to connect the central canals of different osteons.

Step 3: Recognize that perforating canals also communicate with the periosteum, which is the outer fibrous layer of the bone, allowing blood vessels and nerves to enter the bone tissue.

Step 4: Eliminate incorrect options. Epiphyseal plates are growth regions in long bones and are not connected by perforating canals. Osteocytes are mature bone cells located in lacunae and are connected by canaliculi, not perforating canals.

Step 5: Confirm that the correct answer is 'central canals,' as perforating canals connect central canals and communicate with the bone surface via the periosteum.
