Osteons, also known as Haversian systems, are the fundamental functional units of compact bone. They are cylindrical structures that run parallel to the long axis of the bone, providing significant strength and stability. Each osteon consists of concentric layers, or lamellae, surrounding a central Haversian canal, which contains blood vessels and nerves. This organization is crucial for the nourishment and communication required to maintain bone health and integrity, and it also enhances the bone's ability to resist fractures.
