Appendicular Skelton
Dense bone composed of osteons that make up the outer layer of flat, short and irregular bones; major component of long bones
Compact bone
Internal layer of bone in flat, short and irregular bones, and in the epiphyses of long bones
Spongy bone
A bone that is longer than it is wide
Long bone
Thin, flattened, and usually curved
Flat bone
Generally cube shaped and contain mostly spongy bone with an outer layer of compact bone
Short bone
Bones that don’t fit other categories
