As each Harley-Davidson Softail motorcycle declares its styling independence with exclusive components and inspired craftsmanship, the Cross Bones is a bold addition to an already free-spirited family. Many features of the Cross Bones and other Softails are reminiscent of restless riders of the past, whose defiant attitude resonates with those who march to their own beat in any generation.

Bones are a kind of hard endoskeletal connective tissue that is found in all vertebrates. Bones give bodies their structure and protect internal organs. Muscles are attached to bone and they expand and contract to allow movement. The adult human body has 206 bones; the smallest is the stirrup, which is inside the ear. It is less than an inch long. Children are born with 300 bones--some consist of hard connective tissue and others are made of cartilage. Over time, the cartilage hardens and turns to bone and some bones fuse together.

Bones serve as rigid structures to the body and as shields to protect delicate internal organs. They provide housing for the bone marrow, where the blood cells are formed. Bones ... maintain the body's reservoir of calcium. In children, some bones have areas called growth plates. Bones lengthen in these areas until the child reaches full height, at which time the growth plates close. Thereafter, bones grow in thickness rather than in length, based on the body's need for additional bone strength in certain areas.

Bones respond to the presence and absence of forces with changes of size, shape, and density (Wolff, 1892). According to Wolff’s law, the size, shape, and density of a bone change depending on the magnitude and direction of mechanical stress on the bone. Since body weight is the constant stress to bones, the bone density largely depends on the body weight. In other words, heavier persons have higher bone density than lighter persons. Bone density ... largely depends on the diet, gene, activity, life style, and race.

Sure, your arm, wrist, hand, and finger bones are great for picking up the phone, but how are you supposed to run to answer it? Well, with the bones of the legs and feet! Your legs are attached to a circular group of bones called your pelvis. The pelvis is a bowl-shaped structure that supports the spine. It is made up of the two large hip bones in front and behind are the sacrum and the coccyx. The pelvis acts as a tough ring of protection around parts of the digestive system, parts of the urinary system, and parts of the reproductive system.

Bones are ... categorized according to the shapes and the corresponding functions. Short bones include carpals and tarsals. These bones provide limited gliding motions and serves as shock absorbers. Long bones include most of appendicular skeletons such as fibular, tibia, radius, ulnar, metacarpals, metatarsals, and phalanges. These bones provide a frame work of appdendicular skeletons and motions. Flat bones include scapulae, sternum, patellae, and some of the bones in skull.
