What four groups are bones classified in?

Answer 1

Bone types are classified according to their shape. First, we have the long bones. Long bones are wide and are found in your arms and legs. Second, the short bones. These bones are fairly equal-sized in width and length, similar to a cube, and are mostly found in your wrists and ankles. Third, we have flat bones. These are thinner bones that can be either flat or curved and are platelike in nature. Examples of flat bones are the skull, ribs, and breastbone (sternum). Irregular bones are like the parts of a jigsaw puzzle. These are the odd-shaped bones needed to connect to other bones. The hip bones and vertebrae that make up our spine are examples of irregular bones.

Answer 2

* Long bones are characterized by a shaft, the diaphysis, that is much greater in length than width. They are comprised mostly of compact bone and lesser amounts of marrow, which is located within the medullary cavity, and spongy bone. Most bones of the limbs, including those of the fingers and toes, are long bones. The exceptions are those of the wrist, ankle and kneecap. * Short bones are roughly cube-shaped, and have only a thin layer of compact bone surrounding a spongy interior. The bones of the wrist and ankle are short bones, as are the sesamoid bones. * Flat bones are thin and generally curved, with two parallel layers of compact bones sandwiching a layer of spongy bone. Most of the bones of the skull are flat bones, as is the sternum. * Irregular bones do not fit into the above categories. They consist of thin layers of compact bone surrounding a spongy interior. As implied by the name, their shapes are irregular and complicated. The bones of the spine and hips are irregular bones. * Sesamoid bones are bones embedded in tendons. Since they act to hold the tendon further away from the joint, the angle of the tendon is increased and thus the force of the muscle is increased. Examples of sesamoid bones are the patella and the pisiform. Found at http://en.wikipedia.org/wiki/Bone#Types
