Structure and Function of Bones

10–16 To understand the skeletal system, it is important to know the types and

names of major bones, their functions, and where they are located. Regardless of the

size or shape of a bone, the CF used to designate bone is __________ / _____.

10–17 There are four basic types of bones: long, short, flat, and irregular. Long

bonesare longer than they are wide and are slightly curved for strength. Long bones

vary tremendously in size and include those in the thigh (femur), leg (tibia and

fibula), arm (humerus), and fingers and toes (phalanges). Short bones are somewhat

cube-shaped and are nearly equal in length and width. Examples of short bones are

the carpal (wrist) bones and the tarsal (ankle) bones. Flat bonesare broad and thin.

They cover and protect soft body parts, such as the cranial bones, which protect the

brain, and the sternum and ribs, which protect organs in the thorax. Irregular bones

have varied shapes and sizes and are commonly clustered, such as the bones of the

vertebrae and certain bones of the ears and face.

Refer to Figure 10–3 to review the different types of bones.
