Detailed explanation-1: -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: -Compact bone is formed from a number of osteons, which are circular units of bone material and blood vessels. These units allow compact bone to remain hard and compact while still receiving nutrients from the body and disposing of waste through the same channels.
Detailed explanation-3: -Compact bone is found in the diaphyses of long bones of the body, such as the femur, tibia, humerus, metacarpals, metatarsals, phalanges, clavicles, etc. Spongy bone is located at the epiphyses of the long bones, as well as in the ribs, vertebrae and the skull.
