What's the difference between the axial skeleton and the appendicular skeleton?

The axial skeleton is made up of the skull/cranium, jaw (mandible), sternum, ribs, vertebrae (including sacrum and coccyx). The appendicular skeleton is made of the scapula, humerus, ulna, radius, carpals, metacarpals, phalanges (also known as finger bones), ilium, ischium, pubis, femur, patella, tibia, fibula, tarsals, metatarsals, and some more phalanges (also known as toe bones).
