Bones of the skeletal system can be classified into four major types. They are categorized by shape and size. The four main bone classifications are long, short, flat and irregular bones. Long bones are bones that have greater length than width. Examples include arm, leg, finger, and thigh bones.
In the middle of some bones is jelly-like bone marrow, where new cells are constantly being produced for blood, the Merck Manuals noted. Teeth are considered part of the skeletal system but they are not counted as bones. Teeth are made of dentin and enamel, which is strongest substance in your body. Teeth also play a key role in the digestive system.
