Your skeletal system consists of 206 bones that have been classified in two main groups. These groups are known as the axial skeleton and the appendicular skeleton. All bones are covered with outer layer of hard densely packed compact bone. Almost every bone in the body can be placed in the following categories by shape. Long bones and examples of these are humorous, diaphysis, and epiphysis. Shorts bones are almost equal in length and width, examples include the small bones in the wrists and ankles. Flat bones are somewhat thinner and much flatter than other bones. Flat bones, such as those in the skull, protect organs. The scapula, or shoulder blade, is another example of a flat bone. Irregular bones such as facial bones or the vertebrae, have unusual shapes and do not fit into the other categories.
