Question 19 Each complex of central canal and matrix rings in compact bone is known as \( \begin{array}{l}\text { O perforating (Volkmann's) canal } \\ \text { O a canaliculus } \\ \text { an osteon (Haversian system) }\end{array} \)

Did you know that the osteon, also known as the Haversian system, is the fundamental unit of compact bone? These cylindrical structures not only provide strength but also play a crucial role in the life cycle of bone tissue by facilitating nutrient and waste exchange, all while ensuring that our bones can withstand the daily stresses they experience! In practical terms, understanding the osteon is essential for fields like orthopedics and dentistry. For instance, when doctors perform bone grafting or assess bone health, they often look at the integrity of osteons. A well-structured osteon can indicate healthy bone, while disrupted or fewer osteons can signal potential issues, helping guide treatment decisions in various medical scenarios.
