Document Summary

Axial: they are in the midline of the body: skull, sternum, ribs, vertebral column. Appendicular: they are associated with the extremities of the body: pelvis, bones of the arms, bones of the lower extremities. Long bones: humerus: long bone of the arm. Short bones: carpals of the hands. Flat bones: bones of the skull. Spongy (trabecular) it is organized based on lines of stress (the arrangement of the trabeculae is not random). Bone is dynamic and it responds to forces. For example: fossa: an indentation or a shallow depression in a bone line: a ridge of bone. Notch: indentation at the edge of the bone. Examples of these markings can be seen in the pelvis: image. The goal is not to memorize the features but to associate each feature with another anatomical structure. Articulation/joint: where two or more bones come together. There are different kinds of joints, depending on the bones involved.
