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: -A compact bone example would be the significant cortical bones of all long bones, such as those on arms and legs. They are hard and contain yellow bone marrow. These cylindrical bones constitute 80% of the skeletal system’s weight.

Detailed explanation-3: -Compact bone, also known as cortical bone, borders spongy bone and accounts for the remaining 80% of a human skeleton’s bone. In comparison to the spongy bone, it is smooth, firm, and heavy, and it is white, whereas the spongy bone is pink.
