The human skeleton consists of 206 bones divided into two main parts: the axial skeleton (80 bones) and the appendicular skeleton (126 bones). The axial skeleton includes the skull, vertebral column, ribs, and sternum, while the appendicular skeleton comprises the girdles and limbs. Detailed classifications of bones by regions and types are also provided.
