Amazingly, there are over twenty bones that make up the human skull, but only fourteen of these are facial bones. These fourteen bones that most sources normally list are: inferior nasal concha (2), lacrimal bones (2), mandible, maxilla (2),

nasal bones (2), palatine bones (2), vomer, and zygomatic bones (2). These facial bones just listed are found within the anterior and lower part of the skull.

The remaining part of the skull is called the neurocranium. In the neurocranium, also known as the brain case or brain pan, it is the upper and back part of the skull. This is a true protective case for the human brain. Here the following eight bones are located: the occipital bone, two temporal bones, two parietal bones, the sphenoid bone, ethmoid bone, and frontal bone. These are the bones which fuse together to form the case that encloses and protects the brain. The ethmoid and sphenoid bones are used to close up the base (bottom) of the skull. Without these two bones, the brain case is a skull cap.

Also besides knowing the above, historical facts, since the first written records about people were recorded show that artists, anatomists, anthropologists, etc. have been captivated by the make up of the human skull. Knowledge of how to draw the human skull was and is important. Experts note that facial bones can help to shape features in a person's character. They hold muscles that have caused subtle and telling facial expressions to bring works of art to life.
