Quizplus · Accepted Answer

The structure labeled B in the image is an osteon, which is a fundamental structural unit of compact bone tissue. The osteon includes concentric layers of bone tissue called lamellae, which surround a central canal known as the Haversian canal. The Haversian canal contains blood vessels, nerves, and lymphatic vessels that supply and innervate the bone tissue. The periosteum is a fibrous connective tissue membrane that covers the outer surface of bone and contributes to bone growth and repair. The central canal is part of the osteon, and it runs parallel to the long axis of the bone, allowing blood vessels and nerves to travel through it. Therefore, the best choice for the structure labeled B is C) osteon.
