Detailed explanation-1: -Flat bones consist of two layers of compact bone surrounding a layer of spongy bone.
Detailed explanation-2: -Compact bones are present in the outer layer of long bones, while spongy bones are present in the middle of the long bones. The main difference between spongy and compact bones is their structure and function.
Detailed explanation-3: -Both types are found in most bones. Compact bone forms a shell around cancellous bone and is the primary component of the long bones of the arm and leg and other bones, where its greater strength and rigidity are needed. Mature compact bone is lamellar, or layered, in structure.
Detailed explanation-4: -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.
