Shape Classification. The 206 bones that compose the adult skeleton are divided into five categories based on their shapes (Figure 6.6). Their shapes and their functions are related such that each categorical shape of bone has a distinct function.
Classification of Bones. The 206 named bones of the human skeleton are divided into two groups: axial and appendicular. The axial skeleton forms the long axis of the body and includes the bones of the skull, vertebral column, and rib cage. Generally speaking these bones protect, support, or carry other body parts. ...

Types of Bones is a topic within the Skeletal System module of first-level courses in Human Biology, Anatomy & Physiology and similar entry-level courses for careers in the Health Sciences. Typical study or exam questions include giving examples of different types of bones e.g. long bones, short bones, flat bones, irregular bones, sesamoid bones and so on.
Many facial bones, particularly the ones containing sinuses, are classified as irregular bones. Sesamoid Bones.
