Final answer:
In compact bone, blood vessels, nerves, and lymphatics run through the central Haversian canal of osteons, while Volkmann's canals provide passageways between osteons.
Step-by-step explanation:
Blood vessels, nerves, and lymphatics in compact bone travel through the central Haversian canal of an individual osteon. A Volkmann's canal, also known as a perforating canal, provides a passageway for the same types of structures, but between multiple osteons.
The microscopic structural unit of compact bone is called an osteon, or Haversian system. Each osteon is composed of concentric rings of calcified matrix called lamellae. The central canal, or Haversian canal, which is found at the center of the osteon, contains blood vessels, nerves, and lymphatic vessels. These vessels and nerves extend to the periosteum and endosteum through the Volkmann's canals.
