Detailed explanation-1: -Compact bone consists of closely packed osteons or haversian systems. The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix. Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae.

Detailed explanation-2: -Osteons are the functional units of compact bone. The term functional unit means the smallest unit that can carry out one of the organ’s functions. Compact bone is made of cylindrically-shaped osteons connected together. Osteon GIF from Human Anatomy Atlas 2022 +.

Detailed explanation-3: -In osteology, the osteon or haversian system (/həˈvɜːr. ʒən/; named for Clopton Havers) is the fundamental functional unit of much compact bone.

Detailed explanation-4: -Osteons are structural units of compact bone. Each osteon consists of a central canal, which contains nerve filaments and one or two blood vessels, surrounded by lamellae. Lacunae, small chambers containing osteocytes, are arranged concentrically around the central canal.
