The entire group of bones that make up the head is called the skull and it too can be divided into two primary groups: the Cranium and the Facial area.There are eight bones that make up the cranium, and six bones make up the facial area. In addition to the previous bones, there are six tiny bones (three pairs) called ossicles that are located in the ears. There is one final bone of the human skull. It is a single U-shaped bone to which the tongue attaches to and it is called the hyoid bone. That makes a total of 21.
