Bone can be either woven or lamellar (layered). Lamellar bone (compact bone) is stronger, formed of numerous stacked layers and filled with many collagen fibers parallel to other fibers in the same layer. The fibers run in opposite directions in alternating layers, assisting in the bone's ability to resist torsion forces.
The femur is the strongest bone and is an example of a long bone. In the femur, most lamellar (compact) bone is in the shaft or diaphysis. So, the strongest part of a long bone is the shaft because of the compact bone.

The long bone can be divided into two parts the tubular long bones of the limbs(femur, tibia, fibula, humerus, radius and ulna) and the short tubular bones in the hands and feet (metacarpals,metatarsals and phalanges)Each long bone can be divided into three regions, namely the epiphysis,the metaphysis and the diaphysis. The epiphysis is the rounded end of the bone. The metaphysis is the part adjacent to the epiphysis in the adult(the growth plate or physis being closed). It is the part adjacent to the physisin children (growth plate being open). The diaphysis is the cylindrical shaft of the bone.

the thickest part: the end of the bone

well i would assume ity to be the ends (ball joints) as thre centre would easily break
