The diaphysis, or central shaft, contains bone marrow in a marrow cavity. Long bones are longer than they are wide and have a shaft and two ends. These usually represent passageways for vessels and nerves, points of articulation with other bones or points of attachment for tendons and ligaments.Figure 2. The long bone is covered by articular cartilage at either end and contains bone marrow (shown in yellow in this illustration) in the marrow cavity.

There are holes, depressions, smooth facets, lines, projections and other markings.

The vertebrae and some of the bones in the skull are irregular bones.Īll bones have surface markings and characteristics that make a specific bone unique. They are primarily spongy bone that is covered with a thin layer of compact bone. Irregular Bonesīones that are not in any of the above three categories are classified as irregular bones. Most of the bones of the cranium are flat bones. Flat Bonesįlat bones are thin, flattened, and usually curved. Short bones include the bones of the wrist and ankle. They consist primarily of spongy bone, which is covered by a thin layer of compact bone.

Short bones are roughly cube shaped with vertical and horizontal dimensions approximately equal. Long bones include bones of the thigh, leg, arm, and forearm. They are primarily compact bone but may have a large amount of spongy bone at the ends or extremities. They consist of a long shaft with two bulky ends or extremities. Bones that are longer than they are wide are called long bones. The four principal types of bones are long, short, flat and irregular. The bones of the body come in a variety of sizes and shapes.
