Full Answer

Long bones have two ends connected by a shaft. This type of bone is found in the hands, legs, arms and feet, according to Judy Learn of North Seattle Community College. The thigh bone, known as the femur, is one of the best-known examples of a long bone. Flat bones are characterized by their distinctive structure. These bones consist of a layer of spongy bone tissue sandwiched between two pieces of compact bone. The ribs, collarbone and bones that form the top of the skull are flat bones.

The heel bone, vertebrae and pelvic bones are classified as irregular bones because of their complex shapes. Unlike other types of bone, irregular bones tend to have ridges or notches. The short bones look similar to cubes because each one has roughly the same length and width. The bones in the ankles and wrists are examples of short bones.
