axial skeleton | central (80 bones) |

long bone | longer than they are wide, with a thick compact bone exterior |
short bone | almost equal in length and width and contain a thick interior of spongy bone covered by a thin veneer of compact bone |
flat bone | relatively flat, but may be curved, and contain a thin, spongy bone interior covered by a thin veneer of compact bone |
irregular bone | self-explanatory and do not easily fit into any category (vertebral) |
sesamoid bone | small bones that develop in tendons (patella) for protection against wear and tear; form at points of friction |
sutural bone | within the cranium |
functions of the skeletal system | lever system for locomotion, storage for minerals/nutrients, protection for organs/tissues, framework for the body, blood cell formation (hemopolesis) |
epiphyses | enlarged proximal and distal ends of long bones |
diaphysis | middle shaft area of long bones formed by mostly compact bone |
