Study Notes
- Flat bones are thin, flattened, and usually curved with thin layers of compact bone around spongy bone, examples include the skull, ribs, and sternum.
- Irregular bones have irregular shapes and do not fit into other bone classification categories, examples include vertebrae and the hip bone.
- Long bones consist of the diaphysis (shaft made of compact bone) and epiphysis (ends made mostly of spongy bone).
- Structures of a long bone include the periosteum, sharpey's fibers, arteries, articular cartilage, medullary cavity, and bone markings.
- Bone formation involves osteoblasts and osteoclasts thickening bones, with bones forming during development, growth, remodeling, and healing of fractures.
- Functions of bones include protection of organs, movement due to attached skeletal muscles, storage of minerals and fats, and blood cell formation through hematopoiesis.
- The human skeleton has 206 bones, with two basic types of bone tissue: compact bone (dense and smooth) and spongy bone (composed of small needlelike pieces with open spaces).
- Classification of bones includes long bones (e.g. humerus, femur), short bones (e.g. carpals, patella), and sites for muscle, tendon, ligament attachments, as well as passages for nerves and blood vessels.
