Blood vessels, lymphatic vessels, and nerves travel through compact bone via which canals?

The correct answer pertains to Volkmann's canals, which are crucial structures within compact bone. These canals serve as pathways for blood vessels, lymphatic vessels, and nerves to penetrate the bone. They connect the vascular and nerve systems from the outer surface of the bone to the Haversian systems (or osteons) that exist within the bone.

Volkmann's canals run horizontally across the bone, allowing for the transportation of nutrients and waste in and out of the bone matrix, thus playing a vital role in maintaining bone health and function. The presence of these canals ensures that every osteon is adequately supplied with blood and nerves, which is essential for bone remodeling and metabolic activity.

Understanding the functions of Volkmann's canals sheds light on the complex arrangement of vascular and nerve systems in compact bone, highlighting the importance of these connections for skeletal well-being.
